Numbers 18:30-32

Amplified Bible, Classic Edition

³⁰ Therefore you shall say to them, When you have lifted out and held back the best from it [and presented it to the Lord by giving it to yourselves, the Levites], then it shall be counted to [you] the Levites just as if it were the increase of the threshing floor or of the winepress.

³¹ And you may eat it in every place, you and your households, for it is your reward for your service in the Tent of Meeting.

³² And you shall be guilty of no sin by reason of it when you have lifted out and held back the best of it; neither shall you have polluted the holy things of the Israelites, neither shall you die [because of it].
