Exodus 13:2-12

2“Consecrate to me every firstborn male. The first offspring of every womb among the Israelites belongs to me, whether human or animal.”

3Then Moses said to the people, “Commemorate this day, the day you came out of Egypt, out of the land of slavery, because the Lord brought you out of it with a mighty hand. Eat nothing containing yeast.

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

5When the Lord brings you into the land of the Canaanites, Hittites, Amorites, Hivites and Jebusites—the land he swore to your ancestors to give you, a land flowing with milk and honey—you are to observe this ceremony in this month:

6For seven days eat bread made without yeast and on the seventh day hold a festival to the Lord.

7Eat unleavened bread during those seven days; nothing with yeast in it is to be seen among you, nor shall any yeast be seen anywhere within your borders.

8On that day tell your son, ‘I do this because of what the Lord did for me when I came out of Egypt.’

9This observance will be for you like a sign on your hand and a reminder on your forehead that this law of the Lord is to be on your lips. For the Lord brought you out of Egypt with his mighty hand.

10You must keep this ordinance at the appointed time year after year.

11“After the Lord brings you into the land of the Canaanites and gives it to you, as he promised on oath to you and your ancestors,

12you are to give over to the Lord the first offspring of every womb. All the firstborn males of your livestock belong to the Lord.
