Deuteronomy 16:2-4

Lexham English Bible

² And you shall offer the Passover sacrifice to Yahweh your God from among your flock and herd at the place that Yahweh will choose, to let his name dwell there. ³ You shall not eat with it^[a] anything leavened; seven days you shall eat with it^[b] unleavened bread of affliction, because in haste you went out from the land of Egypt, so that you will remember the day of your going out from the land of Egypt all the days of your life. ⁴ And leaven shall not be seen with^[c] you in any of your territory^[d] for seven days, and none of the meat that you will slaughter on the evening on the first day shall remain overnight until morning.
