Exodus 12:41–42

12:41 At the end of the 430 years, on the very day, all the regiments100 of the Lord went out of the land of Egypt. 12:42 It was a night of vigil for the Lord to bring them out from the land of Egypt,101 and so102 on this night all Israel is to keep the vigil103 to the Lord for generations to come.

100	sn This military term is used elsewhere in Exodus (e.g., 6:26; 7:4; 12:17, 50), but here the Israelites are called “the regiments of the Lord.”
101	tn There is some ambiguity in לֵיל שִׁמֻּרִים הוּא לַיהוָה (lel shimmurim hu’ la’adonay [layhveh]). It is likely that this first clause means that Yahweh was on watch for Israel to bring them out, as the next clause says. He was protecting his people (S. R. Driver, Exodus, 102). Then, the night of vigil will be transferred to Israel, who now must keep it “to” him.
102	tn “and so” has been supplied.
103	tn Heb “this night is for Yahweh a vigil for all Israelites for their generations.”
