Deuteronomy 16:3-4

Rotherham(i) 3 Thou shalt not eat therewith, any thing leavened, seven days, shalt thou eat therewith unleavened cakes, the bread of humiliation,––for, in haste, camest thou forth out of the land of Egypt, that thou mayest remember the day when thou camest forth out of the land of Egypt, all the days of thy life. 4 And there shall not be seen with thee leaven, in any of thy bounds, seven days,––neither shall there remain all night of the flesh which thou shalt sacrifice in the evening, on the first day, unto the morning.
