Deuteronomy 16:4-6

Holman Christian Standard Bible

⁴ No yeast is to be found anywhere in your territory for seven days, and none of the meat you sacrifice in the evening of the first day is to remain until morning. ⁵ You are not to sacrifice the Passover animal in any of the towns the Lord your God is giving you. ⁶ You must only sacrifice the Passover animal at the place where Yahweh your God chooses to have His name dwell. Do this in the evening as the sun sets at the same time of day you departed from Egypt.
