1 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.
2 tn “and so” has been supplied.
3 tn Heb “this night is for Yahweh a vigil for all Israelites for their generations.”
4 sn God chose to guide the people with a pillar of cloud in the day and one of fire at night, or, as a pillar of cloud and fire, since they represented his presence. God had already appeared to Moses in the fire of the bush, and so here again is revelation with fire. Whatever the exact nature of these things, they formed direct, visible revelations from God, who was guiding the people in a clear and unambiguous way. Both clouds and fire would again and again represent the presence of God in his power and majesty, guiding and protecting his people, by judging their enemies.
5 tn The infinitive construct here indicates the result of these manifestations – “so that they went” or “could go.”
6 tn These are adverbial accusatives of time.
7 tn The two nouns “cloud” and “darkness” form a nominal hendiadys: “and it was the cloud and the darkness” means “and it was the dark cloud.” Perhaps this is what the Egyptians saw, preventing them from observing Moses and the Israelites.
8 tn Heb “this to this”; for the use of the pronouns in this reciprocal sense of “the one to the other,” see GKC 448 §139.e, n. 3.
9 tc The LXX reads very differently at the end of this verse: “and there was darkness and blackness and the night passed.” B. S. Childs (Exodus [OTL], 218) summarizes three proposals: (1) One takes the MT as it stands and explains it along the lines of the Targum and Jewish exegesis, that there was one cloud that was dark to one group and light to the other. (2) Another tries to reconstruct a verb from the noun “darkness” or make some use of the Greek verb. (3) A third seeks a different meaning for the verb “lit,” “gave light” by comparative philology, but no consensus has been reached. Given that there is no easy solution apart from reconstructing the text, and given that the MT can be interpreted as it is, the present translation follows the MT.
