Matthew Henry's Concise Commentary

15:1-9 The Lord declares that even Moses and Samuel must have pleaded in vain. The putting of this as a case, though they should stand before him, shows that they do not, and that saints in heaven do not pray for saints on earth. The Jews were condemned to different kinds of misery by the righteous judgment of God, and the remnant would be driven away, like the chaff, into captivity. Then was the populous city made desolate. Bad examples and misused authority often produce fatal effects, even after men are dead, or have repented of their crimes: this should make all greatly dread being the occasion of sin in others.
