Numbers 18:17-19

Young's Literal Translation

¹⁷ `Only, the firstling of a cow, or the firstling of a sheep, or the firstling of a goat, thou dost not ransom, holy they [are]: their blood thou dost sprinkle on the altar, and of their fat thou makest perfume, a fire-offering of sweet fragrance to Jehovah,

¹⁸ and their flesh is thine, as the breast of the wave-offering, and as the right leg, it is thine;

¹⁹ all the heave-offerings of the holy things which the sons of Israel lift up to Jehovah I have given to thee and to thy sons, and to thy daughters with thee, by a statute age-during, a covenant of salt, age-during it [is] before Jehovah, to thee and to thy seed with thee.'
