Numbers 28:17-19

Young's Literal Translation

¹⁷ and in the fifteenth day of this month [is] a festival, seven days unleavened food is eaten;

¹⁸ in the first day [is] an holy convocation, ye do no servile work,

¹⁹ and ye have brought near a fire-offering, a burnt-offering to Jehovah: two bullocks, sons of the herd, and one ram, and seven lambs, sons of a year, perfect ones they are for you;
