Deuteronomy 23:7-9

King James Version

⁷ Thou shalt not abhor an Edomite; for he is thy brother: thou shalt not abhor an Egyptian; because thou wast a stranger in his land.

⁸ The children that are begotten of them shall enter into the congregation of the Lord in their third generation.

⁹ When the host goeth forth against thine enemies, then keep thee from every wicked thing.
