Psalm 52:1
52:1 To the chief Musician, Maschil, [A Psalm] of David, when
     Doeg the Edomite came and told Saul, and said unto him,
     David is come to the house of Ahimelech. Why boastest
     thou thyself in mischief, O {a} mighty man? the goodness of
     God [endureth] continually.

     (a) O Doeg, who half consider to be the tyrant Saul, and
         had the power to murder the saints of God.

Psalm 52:2
52:2 Thy tongue deviseth {b} mischiefs; like a sharp razor,
     working deceitfully.

     (b) Your malice moves you by crafty flattery and lies to
         accuse and destroy the innocents.

Psalm 52:5
52:5 God shall likewise {c} destroy thee for ever, he shall take
     thee away, and pluck thee out of [thy] dwelling place, and
     {d} root thee out of the land of the living. Selah.

     (c) Though God forbear for a time, yet at length he will
         recompense your falsehood.
     (d) Even though you seem to be never so sure settled.

Psalm 52:6
52:6 The {e} righteous also shall see, {f} and fear, and shall
     laugh at him:

     (e) For the eyes of the reprobate are shut at God's
         judgments.
     (f) With joyful reverence, seeing that he takes their part
         against the wicked.

Psalm 52:8
52:8 But I [am] like a {g} green olive tree in the house of God:
     I trust in the mercy of God for ever and ever.

     (g) He rejoices to have a place among the servant's of God,
         that he may grow in the knowledge of godliness.

Psalm 52:9
52:9 I will praise thee for ever, because thou hast done {h}
     [it]: and I will wait on thy name; for [it is] good before
     thy saints.

     (h) Executed his vengeance.
