In Exodus 12:2, Yahweh tells Moses that the month of Abib, the month of Exodus, will be the first month in Israel’s calendar. Israel gets a new time with the Exodus. Yahweh informs Moses using the word “head” or “beginning,” which reaches back to Genesis 1:1. The new time of Israel is a new time for the world; of the Exodus, we might say “In the beginning Yahweh made (new) heavens and earth.”
