Leviticus 21:7-8, 23

They are not to marry a woman defiled by prostitution.  , They are not to marry one divorced  by her husband, for the priest is holy to his God. You are to consider him holy since he presents the food of your God. He will be holy to you because I, the LORD who sets you apart, am holy.

But because he has a defect, he must not go near the curtain  or approach the altar. He is not to desecrate my holy places, for I am the LORD who sets them apart.”
