Numbers 28:26-31

‘Also on the day of the firstfruits, when you bring a new grain offering to the LORD at your Feast of Weeks, you shall have a holy convocation. You shall do no customary work. You shall present a burnt offering as a sweet aroma to the LORD: two young bulls, one ram, and seven lambs in their first year, with their grain offering of fine flour mixed with oil: three-tenths of an ephah for each bull, two-tenths for the one ram, and one-tenth for each of the seven lambs; also one kid of the goats, to make atonement for you. Be sure they are without blemish. You shall present them with their drink offerings, besides the regular burnt offering with its grain offering.
