Numbers 28:26-30

And at the time of the first-fruits, when you give an offering of new meal to the Lord at your feast of weeks, there is to be a holy meeting: you may do no field-work: And give a burned offering for a sweet smell to the Lord; two oxen, one male sheep, and seven he-lambs of the first year; And their meal offering, the best meal mixed with oil, three tenth parts for an ox, two tenth parts for a male sheep, And a separate tenth part for every one of the seven lambs; And one he-goat to take away your sin.
