Leviticus 7:36

‘It is a perpetual statute throughout your generations in all your places of habitation: you shall not eat any fat or any blood.’”

‘And did I not choose them from all the tribes of Israel to be My priests, to go up to My altar, to burn incense, to carry an ephod before Me; and did I not give to the house of your father all the fire offerings of the sons of Israel?

Do you not know that those who perform sacred services eat the food of the temple, and those who attend regularly to the altar have their share from the altar?
