Deuteronomy 23:9-11

New Catholic Bible

⁹ The third generation of children born to them can enter the assembly of the Lord.

¹⁰ Camp Sanitation. When you are encamped against your enemies, stay away from everything that is impure. ¹¹ If one of your men among you is unclean because of a nocturnal emission, let him move outside of the camp. He is not to enter the camp.
