15 Every thing that openeth the womb, of all flesh which they offer unto the Lord, both of man and beast, shall be thine: nevertheless the firstborn of man shalt thou surely redeem, and the firstling of unclean beasts shalt thou redeem.
16 And those that are to be redeemed of them from a month old shalt thou redeem, according to thine estimation, for the money of five shekels, after the shekel of the sanctuary (the same is twenty gerahs).
17 But the firstling of an ox, 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 savour unto the Lord.
18 And the flesh of them shall be thine, as the wave breast and as the right thigh, it shall be thine.
19 All the heave offerings of the holy things, which the children of Israel offer unto the Lord, have I given thee, and thy sons and thy daughters with thee, as a due for ever: it is a covenant of salt for ever before the Lord unto thee and to thy seed with thee.
20 And the Lord said unto Aaron, Thou shalt have no inheritance in their land, neither shalt thou have any portion among them: I am thy portion and thine inheritance among the children of Israel.
21 And unto the children of Levi, behold, I have given all the tithe in Israel for an inheritance, in return for their service which they serve, even the service of the tent of meeting.
