Targum Onkelos (or Onqelos; Hebrew: תַּרְגּוּם אֻנְקְלוֹס, Targūm ’Unqəlōs) is the primary Jewish Aramaictargum ("translation") of the Torah, accepted as an authoritative translated text of the Five Books of Moses and thought to have been written in the early second century CE.
Authorship of the Targum Onkelos is traditionally attributed to Onkelos, a famous convert to Judaism in Tannaic times (c. 35–120 CE). According to the Talmud, the essential content of Targum Onkelos was already known in the time of Ezra the Scribe (immediately after the Babylonian Exile). However, it was later forgotten by the masses, and rerecorded by Onkelos.
While the Aramaic translation of the Torah is traditionally attributed to Onkelos, a translation of the Torah into Greek is mentioned in the Talmud as being made by Aquila of Sinope. However, most scholars hold these to be one and the same person. According to Epiphanius, the Greek translation was made by Aquilas before he converted to Judaism, while the Aramaic translation was made after his conversion. This is said to have been under the direct guidance and instruction of Rabbi Yehoshua and Rabbi Eliezer. Indeed, the same biographical stories that the Jerusalem Talmud attributes to Aquila, the Babylonian Talmud attributes to Onkelos. The overwhelming similarities between the biographies of Aquila and Onkelos has led many to conclude they are the same person. Zvi Hirsch Chajes identified the Aramaic "Targum Onkelos" as Aquila's Greek translation, translated once again into Aramaic. Likewise, A.E. Silverstone (1931:73) has shown quite consummately that Aquilas wrote both the Greek and the Aramaic versions, insofar that "both versions betray the same outstanding characteristics."
A modern scholar has argued that the Aramaic translation must date to the late 4th-early 5th centuries, due to reusing language from other midrashim composed at that time, and thus could not have been composed by Aquila/Onkelos (who lived in the 2nd century). Others, dissenting, have concluded that Onkelos' Aramaic translation originated in Israel in the 1st or early 2nd centuries CE, but that its final redaction was done in Babylonia probably in the 4th or 5th century CE. Onkelos' revised translation became the official version used in translating the Torah on each Sabbath day, displacing the earlier Palestinian Aramaic traditions which had been widely used. The Babylonian Talmud refers to the Torah's Aramaic translation (Targum Onkelos) as "targum didan" ("our translation"), as opposed to that of the more ancient Palestinian Targum. The earliest text samples (Exodus 15:9–12 in Hebrew - Aramaic) appear on two Aramaicincantation bowls (5th–7th centuries CE) discovered at Nippur, Babylonia.
In Talmudic times, readings from the Torah within the synagogues were rendered, verse-by-verse, into an Aramaic translation. To this day, the oldest surviving custom with respect to the Yemenite Jewish prayer-rite is the reading of the Torah and the Haftara with the Aramaic translation (in this case, Targum Onkelos for the Torah and Targum Jonathan ben 'Uzziel for the Haftarah). The custom to read the Aramaic Targum each Sabbath day in the synagogue during the weekly Torah lection was eventually abandoned by other communities in Israel, owing largely to the author of the Shulhan Arukh (Orach Chaim §145:3) who did not encourage its practice, saying that they do not understand the meaning of its words.
Where the custom is to read the Aramaic Targum during the public reading of the Torah on Sabbath days, the story of Reuben (Gen 35:22) and the second "Golden Calf" episode (Ex 32:21–25) are read but not translated, as they involve shameful events. Similarly, the Priestly Blessing (Num 6:24–26) is read but not translated, since the blessings are only to be recited in Hebrew.
The reading of the Targum, verse by verse, in conjunction with the Torah that is read aloud on the Sabbath day is not to be confused with a different practice, namely, that of reviewing the entire Parashah before the commencement of the Sabbath, and which practice has its source in the Talmud, and which the codifiers of Jewish law have ruled as Halacha: "A person should complete his portions of scripture along with the community, reading the scripture twice and the targum once (Shnayim mikra ve-echad targum)." Here, the reference is to completing the reading of the Parashah at home or in the Beit Midrash, along with others, reading in tandem, during which reading each verse is repeated twice; once by the reader himself, followed by a repetition of the same verse by the entire group, and lastly by the initial reader himself who cites the Aramaic Targum of Onkelos.
The days in which the Parashah was read depended largely upon custom. Some had it as their custom to break down the reading into two days. Among Yemenite Jews, Wednesday mornings were given over to the first half of the Parashah, while Thursday mornings were given to the second half of the Parashah. Others read the entire Parashah on Thursday mornings, while others on Thursday nights.
Onkelos' Aramaic translation of the Five Books of Moses is almost entirely a word-by-word, literal translation of the Hebrew Masoretic Text, with very little supplemental material in the form of aggadicparaphrase.[dubious – discuss] However, where there are found difficult biblical passages, Onkelos seeks to minimize ambiguities and obscurities. He sometimes employs non-literal aggadic interpretations or expansions in his translated text, usually in those places where the original Hebrew is marked either by a Hebrew idiom, a homonym, or a metaphor, and could not be readily understood otherwise.
The translator is unique in that he avoids any type of personification, or corporeality, with God, often replacing "human-like" characteristics representing God in the original Hebrew with words that convey a more remote and impersonal sense. For example, "my face" (Heb. panai) is replaced by "from before me" (Exodus 33:23), while "beneath his feet" is replaced by "under his throne of glory" (Exodus 24:10), and "The Lord came down upon Mount Sinai" by "The Lord manifested himself upon Mount Sinai" (Exodus 19:20).Samuel David Luzzatto suggests that the translation was originally meant for the "simple people". This view was strongly rebutted by Nathan Marcus Adler in his introduction to his commentary to Targum Onkelos Netinah La-Ger. He often updates the names of biblical nations, coinage and historical sites to the names known in his own post-biblical era.
In matters of halakha, the targum entirely agrees with Rabbi Akiva's opinions. Some authors suggest that Akiva provided for a revised text of the essential base of Targum Onkelos.
Some of the more notable changes made by Onkelos, in which he attempts to convey the underlying meaning of a verse, rather than its literal translation, are as follows:
(Genesis 1:2) (Aramaic: וְאַרְעָא הֲוָת צָדְיָא וְרֵיקָנְיָא, in Hebrew characters) [= "...and the earth was devastated and empty"], instead of "...and the earth was without form and void."
(Genesis 2:7) (Aramaic: הות באדם לְרוּחַ מְמַלְלָא, in Hebrew characters) [= "...and it became in man a speaking spirit"], instead of "...and man became a living soul."
(Genesis 3:5) (Aramaic: וּתְהוֹן כְּרַבְרְבִין, in Hebrew characters), [= "...and you shall be like potentates"], instead of "...and you shall be like gods."
(Genesis 3:15) (Aramaic: הוּא יְהִי דְּכִיר מָה דַּעֲבַדְתְּ לֵיהּ מִלְּקדְמִין וְאַתּ תְּהֵי נָטַר לֵיהּ לְסוֹפָא, in Hebrew characters) [="...he (i.e. Eve's offspring) shall remember what you (i.e. the serpent) did to him at the beginning, but you (i.e. the serpent) shall hold it against him at the end"], instead of "he shall bruise your head, and you shall bruise his heel."
(Genesis 4:16) (Aramaic: וּנְפַק קַיִן מִן קֳדָם יי' וִיתֵיב בַּאֲרַע גָּלֵי וּמְטֻלְטַל דַּהֲוָת חֲשִׁיבָא עֲלוֹהִי מִלְּקַדְמִין כְּגִנְּתָא דְּעֵדֶן, in Hebrew characters) [="And Cain went out from the presence of the Lord, and dwelt in a land of exiles and wandering, which was considered by him beforehand as the Garden of Eden"], instead of "Cain went out from the presence of the Lord, and dwelt in the land of Nod to the east of Eden."
(Genesis 18:8) (Aramaic: וְהוּא מְשַׁמֵּשׁ עִלָּוֵיהוֹן תְּחוֹת אִילָנָא, in Hebrew characters), [= "...and he waited upon them under the tree, etc."], instead of "...and he stood by them under the tree, etc."
(Genesis 20:16) (Aramaic: הָא יְהַבִית אֶלֶף סִלְעִין דִּכְסַף לַאֲחוּיִיךְ הָא הוּא לִיךְ כְּסוּת דִּיקָר חֲלָף דִּשְׁלַחִית דְּבַרְתִּיךְ וַחֲזֵית יָתִיךְ וְיָת כָּל דְּעִמִּיךְ וְעַל כָּל מָא דַּאֲמַרְתְּ אִתּוֹכָחְתְּ, in Hebrew characters) [= "...behold, I have given to your brother one-thousand silver coins in specie. Lo! It is for you an honorable remittance, for my having sent [unto you] and having controlled you; and for my having seen you [in private] and everything that is with you, and how that you have been proven [to be honest] in all the things you have spoken"], instead of "I have given your brother a thousand pieces of silver: behold, he is to you a covering of the eyes, unto all that are with you, and with all other: thus she was reproved."
(Genesis 22:14) (Aramaic:וּפְלַח וְצַלִּי אַבְרָהָם תַּמָּן בְּאַתְרָא הַהוּא. אֲמַר קֳדָם יי' הָכָא יְהוֹן פָּלְחִין דָּרַיָּא. בְּכֵין יִתְאֲמַר בְּיוֹמָא הָדֵין בְּטוּרָא הָדֵין אַבְרָהָם קֳדָם יי' פְּלַח, in Hebrew characters) "And Abraham worshiped and prayed there in that place, and said before God, 'Here shall coming generations worship the Lord.' Wherefore, it shall be said on that day, 'In this mountain Abraham worshiped before God'."], instead of "And Abraham called the name of that place Jehovah-jireh: as it is said to this day, In the mount of the Lord it shall be seen."

(Genesis 31:53) (Aramaic:וְקַיֵּים יעֲקֹב בִּדְדָּחֵיל לֵיהּ אֲבוּהִי יִצחָק, in Hebrew characters) [="...and Jacob made an oath by him whom his father Isaac feared" (i.e. the God of his father, without naming Him)], instead of "...and Jacob sware by the fear of his father Isaac."

(Genesis 43:16) (Aramaic: אֲרֵי עִמִּי אָכְלִין גּוּבְרַיָּא בְּשֵׁירוּתָא, in Hebrew characters) [="...for these men shall dine with me during the late afternoon meal"], instead of "...for these men shall dine with me at noon."
(Genesis 45:27) (Aramaic: וַחֲזָא יָת עֶגְלָתָא וכו' וּשְׁרָת רוּחַ קוּדְשָׁא עַל יַעֲקֹב אֲבוּהוֹן, in Hebrew characters) [="and when he saw the wagons, etc., a holy spirit came over Jacob their father"], instead of "...the spirit of Jacob their father revived."
(Genesis 49:9) (Aramaic: שִׁלְטוֹן יְהֵי בְשֵׁירוּיָא וּבְסוֹפָא יִתְרַבַּא מַלְכָּא מִדְּבֵית יְהוּדָה, in Hebrew characters) [="A [mere] governor he shall be in the beginning, but in the end he shall be anointed king from the House of Judah"], instead of "Judah is a lion's cub"

^Mishnah (Megillah 4:4); Babylonian Talmud (Megillah 3a). In the book She'iltoth by Rav Ahai Gaon (P. Nitzavim § 161), he writes: "And when he reads [from the Torah], a translator must respond [to each verse], and they are to adjust the tone of their voices together [so that they are the same]. But if the translator cannot raise his voice, let the reader [from the Torah] lower his own voice."
^Maimonides, Mishneh Torah, Hil. Tefillah 13:25; Tur and Shulchan Aruch, Orach Chaim 285:1, who writes that one should take care to review the entire weekly biblical lection (Parashah) for that particular week, or what is known as shenayim miqra we'ehad targum, (lit. "two scriptural verses and one [verse] from the Targum"), i.e. reading aloud its verses along with its designated Aramaic translation, known as the Targum. Beyond this, Rabbi Joseph Karo does not say how this should be done.
^The literal words used in the Hebrew text are: "and you shall be like elohim." The word elohim, however, is a Hebrew homonym, having multiple meanings. It can mean either God, angels, judges, potentates (in the sense of "rulers" or "princes"), nobles, and gods (in the lower case). In most English translations of Genesis 3:5 it is rendered as "gods" (in the lower case), and which, according to Onkelos, is a mistranslation and should be translated as "potentates."

^Cf. Philo of Alexandria, The Special Laws ii.1, who wrote that from this verse it is learnt that one should never lightly assay to invoke the name of God.
^Thus explained by Rabbi Zechariah Dhahiri in his commentary Ṣeidah la’derekh (Victuals for the Road) on Genesis 43:16, "For these men shall dine with me baṣa'harayim (בצהרים). It has been translated [in Aramaic] בשירותא, to instruct that it was not really noon time, but at its end, when he eats during the time of the meal at evening. The proof of which is had at what David said, may peace be upon him, 'Evening and morning and at noon I utter my complaint and moan, and he hears my voice' (Ps. 55:17), which [noon time] is actually during the Afternoon Prayer. Moreover, the Sages have already said that that time is when there is but left in the day an hour and a half [before sunset]. This, then, is the matter, `for these men shall dine with me baṣa'harayim` The words of Onkelos are correct" (END QUOTE).

^Onkelos' words are explained by the biblical exegete Rashi in his commentary on the same verse, saying that Onkelos' translation is a play on words and that it is an allusion to King David who, at first, was an important personage during the reign of King Saul, in this case compared to a "cub" (Hebrew: גור), hence: "governor" (Aramaic: שלטון), but in the end, he was like unto a "lion" (Hebrew: אריה) when he was anointed king of Israel.
^In accordance with a teaching in the Jerusalem Talmud (Nedarim 3:9 [13a]): "Rabban Shimon ben Gamliel said: May God forbid! The angel [of death] did not seek to kill Moses, but rather the infant!" Still, the matter is disputed, some holding that it was Moses, Zipporah's bridegroom, whom the angel of death sought to kill for not performing the circumcision on one of their sons, as relayed in the Palestinian Aramaic Targum.
Mechon Mamre has the entire Aramaic text of Targum Onkelos with vowels according to Yemenite manuscripts. The Targum appears as digital text in two different user-friendly versions: (1) The Aramaic targum text with vowels can be viewed in its entirety on its own, either book-by-book or chapter by chapter. (2) The Aramaic targum can be viewed verse-by-verse parallel to the Hebrew text, within files that contain one weekly portion (parshat ha-shavua) at a time. The index to both versions is here; there is also an older version without vowels.
Sefaria has the entire Aramaic text of Targum Onkelos, with some of it translated into English, and each verse hyperlinked to various other texts
