521 To the chief Musician: an instruction. Of David; when Doeg the Edomite came and told Saul, and said unto him, David came to the house of Ahimelech. Why boastest thou thyself in evil, thou mighty man? The loving-kindness of God [abideth] continually.
Matthew Henry's Commentary on Psalm 52:1
Commentary on Psalm 52:1-5
(Read Psalm 52:1-5)
Those that glory in sin, glory in their shame. The patience and forbearance of God are abused by sinners, to the hardening of their hearts in their wicked ways. But the enemies in vain boast in their mischief, while we have God's mercy to trust in. It will not save us from the guilt of lying, to be able to say, there was some truth in what we said, if we make it appear otherwise than it was. The more there is of craft and contrivance in any wickedness, the more there is of Satan in it. When good men die, they are transplanted from the land of the living on earth, to heaven, the garden of the Lord, where they shall take root for ever; but when wicked men die, they are rooted out, to perish for ever. The believer sees that God will destroy those who make not him their strength.
