Jekuthiel ben Isaac Blitz (b. Wittmund, Germany, fl.
1670s) was a rabbi who made the first whole translation of the Hebrew Bible into Yiddish.
[1] Blitz was a corrector of the press in the Hebrew printing-office of Uri Phoebus (Faibush) Halevi in Amsterdam and was commissioned by him to make a translation which finished printing in late 1678.
The translation which was the first of its kind of the entire Old Testament has three introductions; one in Hebrew and one in German written by Blitz and the third in Judæo-German by the printer together with letters patent of the king of Poland Johann III Sobieski and approbations by various rabbis.
Blitz also translated into Judæo-German Levi ben Gerson's "To'aliyyot" on Joshua, Judges, and Samuel, published together with the preceding work.
