Exodus 13:4

1 Then the LORD said to Moses,

2 “Consecrate to Me every firstborn male. The firstborn from every womb among the Israelites belongs to Me, both of man and beast.”

3 So Moses told the people, “Remember this day, the day you came out of Egypt, out of the house of slavery; for the LORD brought you out of it by the strength of His hand. And nothing leavened shall be eaten.

4 Today, in the month of Abib, you are leaving.

5 And when the LORD brings you into the land of the Canaanites, Hittites, Amorites, Hivites, and Jebusites—the land He swore to your fathers that He would give you, a land flowing with milk and honey—you shall keep this service in this month.

6 For seven days you are to eat unleavened bread, and on the seventh day there shall be a feast to the LORD.

7 Unleavened bread shall be eaten during those seven days. Nothing leavened may be found among you, nor shall leaven be found anywhere within your borders.

8 And on that day you are to explain to your son, ‘This is because of what the LORD did for me when I came out of Egypt.’
