3 An Ammonite or a Moabite shall not enter into the assembly of Jehovah; even to the tenth generation shall none belonging to them enter into the assembly of Jehovah for ever: 4 because they met you not with bread and with water in the way, when ye came forth out of Egypt, and because they hired against thee Balaam the son of Beor from Pethor of Mesopotamia, to curse thee. 5 Nevertheless Jehovah thy God would not hearken unto Balaam; but Jehovah thy God turned the curse into a blessing unto thee, because Jehovah thy God loved thee. 6 Thou shalt not seek their peace nor their prosperity all thy days for ever.
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.
