Deuteronomy 16:4-6

English Standard Version Anglicised

^4 (A)No leaven shall be seen with you in all your territory for seven days, ^(B)nor shall any of the flesh that you sacrifice on the evening of the first day remain all night until morning. ⁵ You may not offer the Passover sacrifice within any of your towns that the Lord your God is giving you, ⁶ but at the place that the Lord your God will choose, to make his name dwell in it, there you shall offer the Passover sacrifice, in the evening at sunset, at the time you came out of Egypt.
