Leviticus 7:34-36

Young's Literal Translation

³⁴ `For the breast of the wave-offering, and the leg of the heave-offering, I have taken from the sons of Israel, from the sacrifices of their peace-offerings, and I give them to Aaron the priest, and to his sons, by a statute age-during, from the sons of Israel.'

³⁵ This [is] the anointing of Aaron, and the anointing of his sons out of the fire-offerings of Jehovah, in the day he hath brought them near to act as priest to Jehovah,

³⁶ which Jehovah hath commanded to give to them in the day of His anointing them, from the sons of Israel -- a statute age-during to their generations.
