Deuteronomy 16:4-6

Complete Jewish Bible

⁴ No leaven is to be seen with you anywhere in your territory for seven days. None of the meat from your sacrifice on the first day in the evening is to remain all night until morning. ⁵ You may not sacrifice the Pesach offering in just any of the towns that Adonai your God is giving you; ⁶ but at the place where Adonai your God will choose to have his name live — there is where you are to sacrifice the Pesach offering, in the evening, when the sun sets, at the time of year that you came out of Egypt.
