Numbers 18:16

13 The first-ripe fruits of all that is in their land, which they bring to Yahweh, shall be your; everyone who is clean in your house shall eat of it.

14 Everything devoted in Israel shall be your.

15 Everything that opens the womb, of all flesh which they offer to Yahweh, both of man and animal shall be your: nevertheless the firstborn of man shall you surely redeem, and the firstborn of unclean animals shall you redeem.

16 Those who are to be redeemed of them from a month old shall you redeem, according to your estimation, for the money of five shekels, after the shekel of the sanctuary (the same is twenty gerahs).

17 But the firstborn of a cow, or the firstborn of a sheep, or the firstborn of a goat, you shall not redeem; they are holy: you shall sprinkle their blood on the altar, and shall burn their fat for an offering made by fire, for a sweet savor to Yahweh.

18 The flesh of them shall be your, as the wave-breast and as the right thigh, it shall be your.

19 All the heave-offerings of the holy things, which the children of Israel offer to Yahweh, have I given you, and your sons and your daughters with you, as a portion forever: it is a covenant of salt forever before Yahweh to you and to your seed with you.
