Deuteronomy

On that day they read in the book of Moses in the audience of the people; and therein was found written, that the Ammonite and the Moabite should not come into the congregation of God for ever;

Because they met not the children of Israel with bread and with water, but hired Balaam against them, that he should curse them: howbeit our God turned the curse into a blessing.

The adversary hath spread out his hand upon all her pleasant things: for she hath seen that the heathen entered into her sanctuary, whom thou didst command that they should not enter into thy congregation.

He that is wounded in the stones, or hath his privy member cut off, shall not enter into the congregation of the Lord.

Concerning the Ammonites, thus saith the Lord; Hath Israel no sons? hath he no heir? why then doth their king inherit Gad, and his people dwell in his cities?
