3 "No Ammonite or Moabite or any of their descendants for ten generations may be admitted to the assembly of the Lord . 4 These nations did not welcome you with food and water when you came out of Egypt. Instead, they hired Balaam son of Beor from Pethor in distant Aram-naharaim to curse you. 5 But the Lord your God refused to listen to Balaam. He turned the intended curse into a blessing because the Lord your God loves you. 6 As long as you live, you must never promote the welfare and prosperity of the Ammonites or Moabites.

Matthew Henry's Commentary on Deuteronomy 23:3-6

Commentary on Deuteronomy 23:1-8

(Read Deuteronomy 23:1-8)

We ought to value the privileges of God's people, both for ourselves and for our children, above all other advantages. No personal blemishes, no crimes of our forefathers, no difference of nation, shuts us out under the Christian dispensation. But an unsound heart will deprive us of blessings; and a bad example, or an unsuitable marriage, may shut our children from them.
