The Lord spoke further to Moses, saying, "Consecrate to Me every first-born; man and beast, the first issue of every womb among the Israelites is Mine."
And Moses said to the people, "Remember this day, on which you went free from Egypt, the house of bondage, how the Lord freed you from it with a mighty hand: no leavened bread shall be eaten. You go free on this day, in the month of Abib. So, when the Lord has brought you into the land of the Canaanites, the Hittites, the Amorites, the Hivites, and the Jebusites, which He swore to your fathers to give you, a land flowing with milk and honey, you shall observe in this month the following practice:
"Seven days you shall eat unleavened bread, and on the seventh day there shall be a festival of the Lord. Throughout the seven days unleavened bread shall be eaten; no leavened bread shall be found with you, and no leaven shall be found in all your territory. And you shall explain to your son on that day, 'It is because of what the Lord did for me when I went free from Egypt.'
"And this shall serve you as a sign on your hand and as a reminder on your forehead--in order that the Teaching of the Lord may be in your mouth--that with a mighty hand the Lord freed you from Egypt. You shall keep this institution at its set time from year to year. "And when the Lord has brought you into the land of the Canaanites, as He swore to you and to your fathers, and has given it to you, you shall set apart for the Lord every first issue of the womb: every male firstling that your cattle drop shall be the Lord's. But every firstling ass you shall redeem with a sheep; if you do not redeem it, you must break its neck. And you must redeem every first-born male among your children. And when, in time to come, your son asks you, saying, 'What does this mean?' you shall say to him, 'It was with a mighty hand that the Lord brought us out from Egypt, the house of bondage. When Pharaoh stubbornly refused to let us go, the Lord slew every first-born in the land of Egypt, the first-born of both man and beast. Therefore I sacrifice to the Lord every first male issue of the womb, but redeem every first-born among my sons.'
"And so it shall be as a sign upon your hand and as a symbol on your forehead that with a mighty hand the Lord freed us from Egypt."
