Deuteronomy 23:1-4

1Perhaps a man has sex parts that someone has destroyed or spoiled. That man cannot join with the Lord's people when they meet together.

2If someone was born when his parents were not properly married, he cannot join with the Lord's people. His descendants may not meet with the Lord's people to worship the Lord either. That will continue to the tenth generation of the man's descendants.

3Ammonite and Moabite people also cannot join with the Lord's people when they come together to worship him. Even the tenth generation of their descendants can never do this.

4The people of those nations refused to help you when you were leaving Egypt. They did not give you food or water. Also, they paid Beor's son Balaam to curse you. He came from Pethor in Mesopotamia.
