“Moses said to the people, ‘Remember this day, on which you came out of Egypt, out of the house of slavery, because Yahweh brought you out from there by his strength of hand. No leavened bread shall be eaten. Today in the month of Abib you are going out. When Yahweh brings you into the land of the Canaanites, the Hittites, the Amorites, the Hivites, and the Jebusites, which he swore to your ancestors to give you, a land flowing with milk and honey, you shall keep this observance in this month. Seven days you shall eat unleavened bread, and on the seventh day there shall be festival to Yahweh. Unleavened bread shall be eaten for seven days. No leavened bread shall be seen in your possession, and no leaven shall be seen among you in all your territory. You shall tell your child on that day, ‘It is because of what Yahweh did for me when I came out of Egypt.’ It shall serve for you as a sign on your hand and as a reminder on your forehead, so that the teaching of Yahweh may be on your lips. For with a strong hand Yahweh brought you out of Egypt. You shall keep this ordinance at its proper time from year to year.”
Moses told his people to remember this day and not eat leavened bread. The moth of Abib became Nisan, or what we call today call April. Leaven is a big deal. The feat of unleavened bread is to be observed for seven days. The Israelites should tell their children, why they are doing this. This is a commemoration what Yahweh did for them when they came out of Egypt. Once again there is a mention of the groups that inhabit Canaan.
