TSK · Numbers 18:11

And thou shalt sanctify the breast of the wave offering, and the shoulder of the heave offering, which is waved, and which is heaved up, of the ram of the consecration, [even] of [that] which [is] for Aaron, and of [that] which is for his sons:

His own hands shall bring the offerings of the LORD made by fire, the fat with the breast, it shall he bring, that the breast may be waved [for] a wave offering before the LORD.

¶ And the LORD spake unto Moses, saying,

But if the priest buy [any] soul with his money, he shall eat of it, and he that is born in his house: they shall eat of his meat.

And this shall be the priest's due from the people, from them that offer a sacrifice, whether [it be] ox or sheep; and they shall give unto the priest the shoulder, and the two cheeks, and the maw.
