Matthew Henry on Psalms 129:1-4

The enemies of God's people have very barbarously endeavoured to wear out the saints of the Most High. But the church has been always graciously delivered. Christ has built his church upon a rock. And the Lord has many ways of disabling wicked men from doing the mischief they design against his church. The Lord is righteous in not suffering Israel to be ruined; he has promised to preserve a people to himself.
