Deuteronomy 16:4
Brenton's English Septuagint · Berean Standard Bible
Leaven shall not be seen with thee in all thy borders for seven days, and there shall not be left of the flesh which thou shalt sacrifice at even on the first day until the morning.
No leaven is to be found in all your land for seven days, and none of the meat you sacrifice in the evening of the first day shall remain until morning.
