Numbers 18:13

10 As something most holy, shall ye eat it,—every male, shall eat it, holy, shall it be unto thee.

11 This, therefore, shall be thine—the heave-offering of their gift even all the wave-offerings of the sons of Israel, unto thee, have I given them and unto thy sons and unto thy daughters with thee by a statute age-abiding,—every one that is clean in thy house, shall eat it.

12 All the best of oil, and all the best of new-wine and corn,—the firstfruits thereof which they shall give unto Yahweh, unto thee, have I given them.

13 The firstfruits of all that is in their land which they shall bring in unto Yahweh, thine, shall it be,—every one that is clean in thy house, shall eat it:

14 every devoted thing in Israel, thine, shall it be:

15 every thing that is born first of all flesh that may be offered unto Yahweh among men and among beasts, shall be thine,—only thou shalt, redeem, the firstborn of men, and the firstborn of unclean beasts, shalt thou redeem.

16 And, as to the redemption price thereof, from a month old, shalt thou redeem, by thine estimate five shekels of silver by the shekel of the sanctuary,—twenty gerahs, it is.
