Numbers 28:20

On the fifteenth day of this month shall be a feast. Unleavened bread shall be eaten for seven days.

In the first day shall be a holy convocation. You shall do no regular work,

but you shall offer an offering made by fire, a burnt offering to the LORD: two young bulls, one ram, and seven male lambs a year old. They shall be without defect,

You shall offer one tenth for every lamb of the seven lambs;

and one male goat for a sin offering, to make atonement for you.

You shall offer these in addition to the burnt offering of the morning, which is for a continual burnt offering.
