See here, 1. How the guilt of sin is taken away from us - by the mercy and truth of God, mercy in promising, truth in performing, the mercy and truth which kiss each other in Jesus Christ the Mediator - by the covenant of grace, in which mercy and truth shine so brightly - by our mercy and truth, as the condition of the pardon and a necessary qualification for it - by these, and not by the legal sacrifices, Mic 6:7, Mic 6:8. 2. How the power of sin is broken in us. By the principles of mercy and truth commanding in us the corrupt inclinations are purged out (so we may take the former part); however, by the fear of the Lord, and the influence of that fear, men depart from evil; those will not dare to sin against God who keep up in their minds a holy dread and reverence of him.

By mercy and truth iniquity is purged,.... Or "expiated" (d), and atoned for: not by the mercy and truth of men; not by alms deeds or showing mercy to the poor; nor by speaking truth and keeping promises, and doing justice between man and man; for, though these are duties to be performed, they will not atone for sin; and may be done by persons destitute of the grace of God, and whose iniquities are not purged or pardoned: but by the mercy and truth of God; through his "mercy", in sending Christ to be the propitiation for sin; and through his "truth", in fulfilling his promises concerning Christ; and particularly concerning pardon on the foot of his sacrifice and satisfaction, where mercy and truth have met together: or through the grace and truth come by Jesus Christ; or through his atoning sacrifice, by which he has finished transgression, made an end of sin, and made reconciliation for iniquity; in which there is a rich display of his own and of his father's grace and mercy, truth and faithfulness;

and by the fear of the Lord men depart from evil; having that put into their hearts, and excited and influenced by the grace and goodness of God, men are engaged to abstain from evil, and the appearance of it; it teaches them to deny ungodliness and worldly lusts, and to live soberly and godly in this world.

(d) "expiabitur", Montanus, Vatablus; "expiatur", Tigurine version, Mercerus, Junius & Tremellius, Piscator, Gejerus, Michaelis, Schultens.

By mercy and truth--that is, God's (Psa 85:10); He effects the atonement, or covering of sin; and the principles of true piety incline men to depart from evil; or, "mercy" and "truth" may be man's, indicative of the gracious tempers which work instrumentally in procuring pardon.

purged--expiated (as in Lev 16:33; Isa 27:9, Hebrew).
