Matthew Henry Commentary Psalms 52:1-5

"Why boastest thou thyself in mischief, O mighty man? The lovingkindness of God [endureth] continually. Thy tongue deviseth very wickedness, Like a sharp razor, working deceitfully. Thou lovest evil more than good, And lying rather than to speak righteousness. Selah Thou lovest all devouring words, thou deceitful tongue. God will likewise destroy thee for ever; He will take thee up, and pluck thee out of thy tent, And root thee out of the land of the living. Selah" — Psalms 52:1-5 (ASV)

Those who glory in sin, glory in their shame. The patience and forbearance of God are abused by sinners, resulting in the hardening of their hearts in their wicked ways.

But the enemies boast in vain 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 different from what it was. The more craft and contrivance there is in any wickedness, the more of Satan there is in it.

When good people die, they are transplanted from the land of the living on earth to heaven, the garden of the Lord, where they will take root forever; but when wicked people die, they are rooted out to perish forever. The believer sees that God will destroy those who do not make Him their strength.
