Deuteronomy 16:1-4, 5-7, 16-17

Observe the month of Abib by celebrating the Passover to GOD, your God. It was in the month of Abib that GOD, your God, delivered you by night from Egypt. Offer the Passover-Sacrifice to GOD, your God, at the place GOD chooses to be worshiped by establishing his name there. Don’t eat yeast bread with it; for seven days eat it with unraised bread, hard-times bread, because you left Egypt in a hurry—that bread will keep the memory fresh of how you left Egypt for as long as you live. There is to be no sign of yeast anywhere for seven days. And don’t let any of the meat that you sacrifice in the evening be left over until morning.

Don’t sacrifice the Passover in any of the towns that GOD, your God, gives you other than the one GOD, your God, designates for worship; there and there only you will offer the Passover-Sacrifice at evening as the sun goes down, marking the time that you left Egypt. Boil and eat it at the place designated by GOD, your God. Then, at daybreak, turn around and go home.

All your men must appear before GOD, your God, three times each year at the place he designates: at the Feast-of-Unraised-Bread (Passover), at the Feast-of-Weeks, and at the Feast-of-Booths. No one is to show up in the Presence of GOD empty-handed; each man must bring as much as he can manage, giving generously in response to the blessings of GOD, your God. * * *
