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 tn The translation has “regular” instead of “continually,” because they will be preparing this twice a day.
5 tn The relative clause identifies the place in front of the Tent as the place that Yahweh would meet Moses. The main verb of the clause is אִוָּעֵד (’ivva’ed), a Niphal imperfect of the verb יָעַד (ya’ad), the verb that is cognate to the name “tent of meeting” – hence the name. This clause leads into the next four verses.
6 tn Heb “and [then] they will wash.”
7 tn The verb is “it will be.”
8 tn Heb “for his seed.”
9 tn Or “for generations to come”; it literally is “to their generations.”
sn The symbolic meaning of washing has been taught throughout the ages. This was a practical matter of cleaning hands and feet, but it was also symbolic of purification before Yahweh. It was an outward sign of inner spiritual cleansing, or forgiveness. Jesus washed the disciples feet (Jn 13) to show this same teaching; he asked the disciples if they knew what he had done (so it was more than washing feet). In this passage the theological points for the outline would be these: I. God provides the means of cleansing; II. Cleansing is a prerequisite for participating in the worship, and III. (Believers) priests must regularly appropriate God’s provision of cleansing.
10 sn The instruction for the Sabbath at this point seems rather abrupt, but it follows logically the extended plans of building the sanctuary. B. Jacob, following some of the earlier treatments, suggests that these are specific rules given for the duration of the building of the sanctuary (Exodus, 844). The Sabbath day is a day of complete cessation; no labor or work could be done. The point here is that God’s covenant people must faithfully keep the sign of the covenant as a living commemoration of the finished work of Yahweh, and as an active part in their sanctification.
