Deuteronomy 23:9 (WEB)
Context Reading
7You 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. 8The children of the third generation who are born to them may enter into Yahweh’s assembly. 9When you go out and camp against your enemies, then you shall keep yourselves from every evil thing. 10If 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; 11but it shall be, when evening comes, he shall bathe himself in water. When the sun is down, he shall come within the camp.
