Nehemiah 13:1-3 - Israel Separates Itself
1 On that day they read in the book of Moses in the hearing of the people; and in it was found written, that the Ammonite and the Moabite should not come into the congregation of God forever; 2 Because they met not the children of Israel with bread and with water, but hired Balaam against them, that he should curse them: however our God turned the curse into a blessing. 3 Now it came to pass, when they had heard the law, that they separated from Israel all the mixed multitude.
