Numbers 28:26-31

On the day of firstfruits, when you present an offering of new grain to the LORD during the Feast of Weeks, you are to hold a sacred assembly; you must not do any regular work.

Present a burnt offering of two young bulls, one ram, and seven male lambs a year old as a pleasing aroma to the LORD,

together with their grain offerings of fine flour mixed with oil—three-tenths of an ephah with each bull, two-tenths of an ephah with the ram,

and a tenth of an ephah with each of the seven lambs.

Include one male goat to make atonement for you.

Offer them with their drink offerings in addition to the regular burnt offering and its grain offering. The animals must be unblemished.
