Numbers 28:18

15 And one he-goat for a sin-offering unto Jehovah; it shall be offered besides the continual burnt-offering, and the drink-offering thereof.

16 And in the first month, on the fourteenth day of the month, is Jehovah`s passover.

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

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

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

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

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