Numbers 28:18KJV

16And in the fourteenth day of the first month the passover of the LORD.

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

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

19But ye shall offer a sacrifice made by fire 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 flour mingled with oil: three tenth deals shall ye offer for a bullock, and two tenth deals for a ram;
