Numbers 28:16-22

16And in the first month, on the fourteenth day of the month, is the LORD’S passover.

17And on the fifteenth day of this month shall be a feast: seven days shall unleavened bread be eaten.

18In the first day shall be an holy convocation; ye shall do no servile work:

19but ye shall offer an offering made by fire, a burnt offering unto the LORD; two young bullocks, and one ram, and seven he-lambs of the first year: they shall be unto you without blemish:

20and their meal offering, fine flour mingled with oil: three tenth parts shall ye offer for a bullock, and two tenth parts for the ram;

21a several tenth part shalt thou offer for every lamb of the seven lambs;

22and one he-goat for a sin offering, to make atonement for you.
