'Congregation of the Lord' in the Bible

None that is gelded, or hath his privy members cut off, shall come into the congregation of the LORD.

And he that is a whore's child shall not come in the congregation of the LORD; no, in the tenth generation he shall not enter into the congregation of the LORD.

The Ammonites and the Moabites shall not come into the congregation of the LORD; no, not in the tenth generation, no they shall never come in to the congregation of the LORD,

The children that are begotten of them shall come into the congregation of the LORD in the third generation.
