Deuteronomy 23:6-8

American Standard Version

⁶ Thou shalt not seek their peace nor their prosperity all thy days for ever.

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.
