Deuteronomy 16:1-8 - The Festival Of Passover
1 Observe the month of Abib, and keep the Passover to the LORD your God; for in the month of Abib the LORD your God brought you forth out of Egypt by night. 2 You shall sacrifice the Passover to the LORD your God, of the flock and the herd, in the place which the LORD shall choose, to cause his name to dwell there. 3 You shall eat no leavened bread with it. You shall eat unleavened bread with it seven days, even the bread of affliction; for you came forth out of the land of Egypt in haste: that you may remember the day when you came forth out of the land of Egypt all the days of your life. 4 No yeast shall be seen with you in all your borders seven days; neither shall any of the flesh, which you sacrifice the first day at evening, remain all night until the morning. 5 You may not sacrifice the Passover within any of your gates, which the LORD your God gives you; 6 but at the place which the LORD your God shall choose, to cause his name to dwell in, there you shall sacrifice the Passover at evening, at the going down of the sun, at the season that you came forth out of Egypt. 7 You shall roast and eat it in the place which the LORD your God shall choose: and you shall turn in the morning, and go to your tents. 8 Six days you shall eat unleavened bread. On the seventh day shall be a solemn assembly to the LORD your God; you shall do no work.
