(9) Purge away.--Rather, put a cover on. So Cicero speaks of political crimes being covered by the plea of friendship.

Our sins.--How is this to be taken in connection with Psalm 79:8? Does the psalmist admit guilt in his own generation, as well as in those of former times? Or is he thinking only of the inherited guilt and punishment? The general tone of post-exile psalms inclines towards the latter view.

Verse 9. - Help us, O God of our salvation, for the glory of thy Name. The calamities suffered have not extinguished all faith or hope. God is still the God of Israel's salvation, i.e. the God from whom alone salvation can be obtained and may be expected. He is entreated to come to Israel's aid, not for their sakes, as they are wholly undeserving, but for his own glory (comp. Exodus 32:12; Numbers 14:13; Deuteronomy 9:28; and Exodus 32:27). And deliver us, and purge away our sins; literally, make atonement for our sins (Exodus 30:15); i.e. "cancel them" (Cheyne), or "forgive them" (Hengstenberg, Kay). For thy Name's sake (comp. Psalm 23:3; Psalm 25:11; Psalm 34:3; Ezekiel 36:22).

79:6-13 Those who persist in ignorance of God, and neglect of prayer, are the ungodly. How unrighteous soever men were, the Lord was righteous in permitting them to do what they did. Deliverances from trouble are mercies indeed, when grounded upon the pardon of sin; we should therefore be more earnest in prayer for the removal of our sins than for the removal of afflictions. They had no hopes but from God's mercies, his tender mercies. They plead no merit, they pretend to none, but, Help us for the glory of thy name; pardon us for thy name's sake. The Christian forgets not that he is often bound in the chain of his sins. The world to him is a prison; sentence of death is passed upon him, and he knows not how soon it may be executed. How fervently should he at all times pray, O let the sighing of a prisoner come before thee, according to the greatness of thy power preserve thou those that are appointed to die! How glorious will the day be, when, triumphant over sin and sorrow, the church beholds the adversary disarmed for ever! while that church shall, from age to age, sing the praises of her great Shepherd and Bishop, her King and her God.Help us, O God of our salvation, for the glory of thy name,.... Help us out of the troubles in which we are; enable us to bear them with patience, and without murmuring, while it is thy pleasure to continue them; assist us against our powerful enemies, and strengthen us to do our duty; afford us more grace, and fresh supplies of it in our time of need: the arguments enforcing these petitions are, because God is "the God of salvation", to whom it belongs, of whom it is, and of him only to be expected; he is the sole author and giver of it; and because to help and save is for the glory of his name, which is great in the salvation of his people:

and deliver us; out of the hands of all our enemies, and out of all our afflictions, and out of this low estate in which we are:

and purge away our sins for thy name's sake; which were the cause of all calamities and distress, and which can only be purged away by the blood and sacrifice of Christ, Hebrews 1:3, the word signifies to "expiate" (i) sin, or atone for it; which was the work and business of Christ our High Priest, who has made reconciliation for sin, finished, made an end of it, and put it away by the oblation of himself, for the sake of which God is propitious; and so the words may be rendered, "be propitious to our sins" (k): or merciful to our unrighteousnesses, for the sake of Christ the great propitiation; or through the propitiatory sacrifice to be offered up by him; or, in other words, "cover our sins" (l); which is also the sense of the phrase, that they may be seen no more; pardon and forgive them for Christ's sake; see Psalm 32:1.
