Matthew Henry on Deuteronomy 21:15-17
This law restrains men from disinheriting their eldest sons out of mere caprice, and without just provocation.
I. The case here put (Deu 21:15) is very instructive. 1. It shows the great mischief of having more wives than one, which the law of Moses did not restrain, probably in hopes that men's own experience of the great inconvenience of it in families would at last put an end to it and make them a law to themselves.
