Numbers 28:16-22

16And on the fourteenth day of the first month is the passover of the LORD. 17And on the fifteenth day of this month is the feast: seven days shall unleavened bread be eaten. 18On the first day shall be an holy convocation; in it ye shall do no manner of servile work: 19But ye shall offer a sacrifice made by fire for a burnt offering to the LORD; two young bulls, and one ram, and seven lambs of the first year: they shall be to you without blemish: 20And their meat offering shall be of flour mixed with oil: three tenth parts shall ye offer for a bull, and two tenth parts for a ram; 21A tenth part shalt thou offer for every lamb, throughout the seven lambs: 22And one goat for a sin offering, to make an atonement for you.
