Deuteronomy 18:3-5

Names of God Bible

³ This is what the people owe the priests whenever they sacrifice an ox, a sheep, or a goat: the shoulder, jaws, and stomach. ⁴ Also, give them the first produce harvested: grain, new wine, olive oil, and the first wool you shear from your sheep. ⁵ Out of all your tribes, Yahweh your Elohim has chosen the Levites and their descendants to do the work of serving in the name of Yahweh forever.
