Numbers 28:27

25On the seventh day you shall have a holy convocation. You shall do no regular work.

26“‘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;

27but you shall offer a burnt offering for a pleasant aroma to the LORD: two young bulls, one ram, seven male lambs a year old;

28and their meal offering, fine flour mixed with oil, three tenths for each bull, two tenths for the one ram,

29one tenth for every lamb of the seven lambs;
