Deuteronomy 23:7-9

American Standard Version

⁷ Thou shalt not abhor an Edomite; for he is thy brother: thou shalt not abhor an Egyptian; because thou wast a sojourner in his land. ⁸ The children of the third generation that are born unto them shall enter into the assembly of Jehovah.

⁹ When thou goest forth in camp against thine enemies, then thou shalt keep thee from every evil thing.
