Numbers 28:28

On the seventh day you shall have a holy convocation. You shall do no regular work.

“‘Also in the day of the first fruits, when you offer a new meal offering to the LORD in your feast of weeks, you shall have a holy convocation. You shall do no regular work;

but you shall offer a burnt offering for a pleasant aroma to the LORD: two young bulls, one ram, seven male lambs a year old;

one tenth for every lamb of the seven lambs;

and one male goat, to make atonement for you.

Besides the continual burnt offering and its meal offering, you shall offer them and their drink offerings. See that they are without defect.
