Deuteronomy 16:4-6

Douay-Rheims 1899 American Edition

⁴ No leaven shall be seen in all thy coasts for seven days, neither shall any of the flesh of that which was sacrificed the first day in the evening remain until morning.

⁵ Thou mayst not immolate the phase in any one of thy cities, which the Lord thy God will give thee:

⁶ But in the place which the Lord thy God shall choose, that his name may dwell there: thou shalt immolate the phase in the evening, at the going down of the sun, at which time thou camest out of Egypt.
