Numbers 28:25-29

On the seventh day you shall have a holy assembly; you shall do no laborious work.

‘Also on the day of the first fruits, when you present a new grain offering to the Lord in your Feast of Weeks, you shall have a holy assembly; you shall do no laborious work.

But you shall offer a burnt offering as a soothing aroma to the Lord: two bulls, one ram, and seven male lambs one year old;

and as their grain offering, fine flour mixed with oil: three-tenths of an ephah for each bull, two-tenths for the one ram,

and a tenth for each of the seven lambs;
