“"O God, deliver me from the hand of the sinner" (ver. 4). Generally, sinners, among whom is toiling he that is now to be delivered from captivity: he that now crieth, "Unhappy man I, who shall deliver me from the body of this death? The Grace of God through Jesus Christ our Lord." Within is a foe, that law in the members; there are without also enemies: unto what cryest thou? Unto Him, to whom hath been cried, "From my secret sins cleanse me, O Lord, and from strange sins spare Thy servant." ...But these sinners are of two kinds: there are some that have received Law, there are others that have not received: all the heathen have not received Law, all Jews and Christians have received Law. Therefore the general term is sinner; either a transgressor of the Law, if he hath received Law; or only unjust without Law, if he hath not received the Law. Of both kinds speaketh the Apostle, and saith, "They that without Law have sinned, without Law shall perish, and they that in the Law have sinned, by the Law shall be judged." But thou that amid both kinds dost groan, say to God that which thou hearest in the Psalm, "My God, deliver me from the hand of the sinner." Of what sinner? "From the hand of him that transgresseth the Law, and of the unjust man." He that transgresseth the Law is indeed also unjust; for not unjust he is not, that transgresseth the Law: but every one that transgresseth the Law is unjust, not every unjust man doth transgress the Law. For, "Where there is not a Law," saith the Apostle, "neither is there transgression." They then that have not received Law, may be called unjust, transgressors they cannot be called. Both are judged after their deservings. But I that from captivity will to be delivered through Thy grace, cry to Thee, "Deliver me from the hand of the sinner." What is, from the hand of him? From the power of him, that while he is raging, he lead me not unto consenting with him; that while he lieth in wait, he persuade not to iniquity. "From the hand of the sinner and of the unjust man."...”

“Deliver me, O my God, out of the hand of the wicked,.... Meaning Absalom his son, as Arama, who had risen up in rebellion against him; and he may not only intend him, but all those wicked men that had joined with him: it was David's mercy he had a covenant God to go to, and could claim his interest in him, who had power to deliver him, and from whom he might expect it; out of the hand of the unrighteous and cruel man; or "leavened" (s); a sour ill natured man; one leavened with malice and wickedness: perhaps Ahithophel is intended. It may be applied to any wicked, lawless, and tyrannical persecutor of God's people; and particularly to the lawless and wicked one, the man of sin, the son of perdition, antichrist, Th2 2:4. (s) "malitiae fermento prorsus corrupti", Michaelis, "secundum", Gejerum & Gussetium; so Ainsworth.”
