Numbers 18:11-19

¹¹And this shall be to you of the first-fruits of their gifts, of all the wave-offerings of the children of Israel; to thee have I given them and to thy sons and thy daughters with thee, a perpetual ordinance; every clean person in thy house shall eat them.

¹²Every first-offering of oil, and every first-offering of wine, their first-fruits of corn, whatsoever they may give to the Lord, to thee have I given them.

¹³All the first-fruits that are in their land, whatsoever they shall offer to the Lord, shall be thine: every clean person in thy house shall eat them.

¹⁴Every devoted thing among the children of Israel shall be thine.

¹⁵And every thing that opens the womb of all flesh, whatsoever they bring to the Lord, whether man or beast, shall be thine: only the first-born of men shall be surely redeemed, and thou shalt redeem the first-born of unclean cattle.

¹⁶And the redemption of them shall be from a month old; their valuation of five shekels—it is twenty oboli according to the holy shekel.

¹⁷But thou shalt not redeem the first-born of calves and the first-born of sheep and the first-born of goats; they are holy: and thou shalt pour their blood upon the altar, and thou shalt offer the fat as a burnt-offering for a smell of sweet savour to the Lord.

¹⁸And the flesh shall be thine, as also the breast of the wave-offering and as the right shoulder, it shall be thine.

¹⁹Every special offering of the holy things, whatsoever the children of Israel shall specially offer to the Lord, I have given to thee and to thy sons and to thy daughters with thee, a perpetual ordinance: it is a covenant of salt for ever before the Lord, for thee and thy seed after thee.
