Matthew Henry on 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.
