Deuteronomy 23:9

You shall not seek their peace nor their prosperity all your days forever.

You shall not abhor an Edomite, for he is your brother. You shall not abhor an Egyptian, because you lived as a foreigner in his land.

The children of the third generation who are born to them may enter into the LORD’s assembly.

If there is among you any man who is not clean by reason of that which happens to him by night, then shall he go outside of the camp. He shall not come within the camp;

but it shall be, when evening comes, he shall bathe himself in water. When the sun is down, he shall come within the camp.

You shall have a place also outside of the camp where you go relieve yourself.
