Deuteronomy 16:4-6

New Life Version

⁴ For seven days there is to be no yeast around in all your land. And none of the flesh you give in worship on the evening of the first day will be kept through the night until morning. ⁵ You are not allowed to give the Passover gift in any of your towns the Lord your God gives you. ⁶ But give it at the place where the Lord your God chooses to put His name. You must kill the Passover gift in the evening when the sun goes down, at the time that you came out of Egypt.
