Matthew 9 - Matthew Henry's Concise Commentary on the Bible

Christ casts out a dumb spirit.

Of the two, better a dumb devil than a blaspheming one. Christ's cures strike at the root, and remove the effect by taking away the cause; they open the lips, by breaking Satan's power in the soul. Nothing can convince those who are under the power of pride. They will believe anything, however false or absurd, rather than the Holy Scriptures; thus they show the enmity of their hearts against a holy God. (Mt 9:35-38)
