Numbers 28:18

14And their drink offerings shall be half an hin of wine unto a bullock, and the third part of an hin unto a ram, and a fourth part of an hin unto a lamb: this is the burnt offering of every month throughout the months of the year.

15And one kid of the goats for a sin offering unto the Lord shall be offered, beside the continual burnt offering, and his drink offering.

16And in the fourteenth day of the first month is the passover of the Lord.

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

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

19But ye shall offer a sacrifice made by fire for a burnt offering unto the Lord; two young bullocks, and one ram, and seven lambs of the first year: they shall be unto you without blemish:

20And their meat offering shall be of flour mingled with oil: three tenth deals shall ye offer for a bullock, and two tenth deals for a ram;

21A several tenth deal shalt thou offer for every lamb, throughout the seven lambs:

22And one goat for a sin offering, to make an atonement for you.
