Numbers 18:13

10 In the most holy [place] shalt thou eat it; every male shall eat it: it shall be holy to thee.

11 And 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.

12 All 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.

13 [And] 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.

14 Every thing devoted in Israel shall be thine.

15 Every 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.

16 And 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.
