Nehemiah 13:1-2
Nehemiah 13: 1 to 2
1 On that day they read in the book of Moses in the audience of the people, and in it was found written that an Ammonite and a Moabite should not enter into the assembly of God forever,
2 because they did not meet the sons of Israel with bread and with water, but hired Balaam against them, to curse them. However our God turned the curse into a blessing.
