[12:1] 1 sn Chapter 12 details the culmination of the ten plagues on Egypt and the beginning of the actual deliverance from bondage. Moreover, the celebration of this festival of Passover was to become a central part of the holy calendar of Israel. The contents of this chapter have significance for NT studies as well, since the Passover was a type of the death of Jesus. The structure of this section before the crossing of the sea is as follows: the institution of the Passover (12:1-28), the night of farewell and departure (12:29-42), slaves and strangers (12:43-51), and the laws of the firstborn (13:1-16). In this immediate section there is the institution of the Passover itself (12:1-13), then the Unleavened Bread (12:14-20), and then the report of the response of the people (12:21-28).
[12:1] 2 tn Heb “and Yahweh said.”
[13:1] 4 sn This next section seems a little confusing at first glance: vv. 1 and 2 call for the dedication of the firstborn, then vv. 3-10 instruct concerning the ritual of the Feast of Unleavened Bread, and then vv. 11-16 return to the firstborn. B. Jacob (Exodus, 360) explains that vv. 3-16 contain a sermon, in which Moses “began his speech by reminding the people of the events which had just occurred and how they would be recalled by them in the future,” and then he explained the rulings that went along with it. So the first two verses state the core of the sermon, a new command calling for the redeemed (firstborn) to be sanctified. The second portion stresses that God requires the redeemed to remember their redemption by purifying themselves (3-10). The third section (11-16) develops the theme of dedication to Yahweh. The point is that in view of God’s mighty redemption, the redeemed (represented by the firstborn) must be set apart for Yahweh’s service.
