25 Seven days shalt thou offer a kid daily for a sin-offering, and a calf of the herd, and a ram out of the flock: they shall sacrifice them unblemished for seven days:

27 And it shall come to pass from the eighth day and onward, the priests shall offer your whole-burnt-offerings on the altar, and your peace-offerings; and I will accept you, saith the Lord.
