2 Esdras (Nehemias) 13:1-2

And on that day they read in the book of Moses in the hearing of the people. And therein was found written, that the Ammonites and the Moabites should not come in to the church of God for ever. Because they met not the children of Israel with bread and water: and they hired against them Balaam, to curse them; and our God turned the curse into blessing.
