Matthew Henry's Concise Commentary

58:1-2 The Holy Spirit had hypocrites of every age in view. Self-love and timid Christians may say, Spare thyself; dislike to the cross and other motives will say, Spare the rich and powerful; but God says, Spare not: and we must obey God, not men. We all need earnestly to pray for God's assistance in examining ourselves. Men may go far toward heaven, yet come short; and they may go to hell with a good reputation.
