Numbers 18:11-19

¹¹And this is thine; the heave-offering of their gift, with all the wave-offerings of the children of Israel: I have given them to thee, and to thy sons, and to thy daughters with thee, by a statute for ever: every one that is clean in thy house shall eat of it.

¹²All the best of the oil, and all the best of the wine, and of the wheat, the first-fruits of them which they shall offer to the LORD, them have I given to thee.

¹³And whatever is first ripe in the land, which they shall bring to the LORD, shall be thine; every one that is clean in thy house shall eat of it.

¹⁴Every thing devoted in Israel shall be thine.

¹⁵Every thing that openeth the matrix in all flesh, which they bring to the LORD, whether of men or beast, shall be thine: nevertheless, the first born of man shalt thou surely redeem, and the firstling of unclean beasts shalt thou redeem.

¹⁶And those that are to be redeemed from a month old shalt thou redeem, according to thy estimation, for the money of five shekels, after the shekel of the sanctuary, which is twenty gerahs.

¹⁷But the firstling of a cow, or the firstling of a sheep, or the firstling of a goat, thou shalt not redeem; they are holy: thou shalt sprinkle their blood upon the altar, and shalt burn their fat for an offering made by fire, for a sweet savor to the LORD.

¹⁸And the flesh of them shall be thine, as the wave-breast and as the right shoulder are thine

¹⁹All the heave-offerings of the holy things, which the children of Israel offer to the LORD, have I given to thee, and to thy sons and thy daughters with thee, by a statute for ever: it is a covenant of salt for ever before the LORD to thee and to thy seed with thee.
