Deuteronomy 16:2-4 English Standard Version Anglicised (ESVUK)
2 And you shall offer the Passover sacrifice to the Lord your God, from the flock or the herd, at the place that the Lord will choose, to make his name dwell there. 3 You shall eat no leavened bread with it. For seven days you shall eat it with unleavened bread, the bread of affliction—for you came out of the land of Egypt in haste—that all the days of your life you may remember the day when you came out of the land of Egypt. 4 No leaven shall be seen with you in all your territory for seven days, nor shall any of the flesh that you sacrifice on the evening of the first day remain all night until morning.
