Leviticus 21:6

“Also let the priests who come near to Yahweh set themselves apart as holy, lest Yahweh break out against them.”

‘Then the priest shall offer it up in smoke on the altar as food, an offering by fire to Yahweh.

Then Moses said to Aaron, “It is what Yahweh spoke, saying, ‘By those who come near Me I will be treated as holy, And before all the people I will be glorified.’” So Aaron kept silent.

‘And you shall not give any of your seed to pass them over to Molech, nor shall you profane the name of your God; I am Yahweh.

‘Therefore, you shall set him apart as holy, for he brings near the food of your God; he shall be holy to you; for I Yahweh, who makes you holy, am holy.

“Speak to Aaron, saying, ‘No man of your seed throughout their generations who has a defect shall come near to offer the food of his God.

‘No man among the seed of Aaron the priest who has a defect shall approach to bring near the offerings to Yahweh by fire; since he has a defect, he shall not approach to bring near the food of his God.

Then I said to them, “You are holy to Yahweh, and the utensils are holy; and the silver and the gold are a freewill offering to Yahweh, the God of your fathers.

“You are presenting defiled food upon My altar. But you say, ‘How have we defiled You?’ In that you say, ‘The table of Yahweh is to be despised.’
