Leviticus 21:7

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

‘A widow or a divorced woman or one who is profaned by harlotry, these he may not take; but rather he shall take a virgin of his own people as a wife,

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.

“And they shall not take a widow or a divorced woman as a wife but shall take virgins from the seed of the house of Israel or a widow who is the widow of a priest.
