Targum Pseudo-Jonathan is a western targum (translation) of the Torah (Pentateuch) from the land of Israel (as opposed to the eastern Babylonian Targum Onkelos). Its correct title was originally Targum Yerushalmi (Jerusalem Targum), which is how it was known in medieval times. But because of a printer's mistake it was later labeled Targum Jonathan, in reference to Jonathan ben Uzziel. Some editions of the Pentateuch continue to call it Targum Jonathan to this day. Most scholars refer to the text as Targum Pseudo-Jonathan. This targum is more than a mere translation. It includes much Aggadic material collected from various sources as late as the Midrash Rabbah as well as earlier material from the Talmud. It is effectively a combination of a commentary and a translation. In the portions where it is pure translation, it often agrees with the Targum Onkelos. The date of its composition is disputed. It cannot have been completed before the Arab conquest as it refers to Mohammad's wife Fatima, but might have been initially composed in the 4th Century CE. However, some scholars date it in the 14th Century.
