(22) This verse, beginning with Pe, was apparently a later addition. Not only is it an isolated line, interfering with the alphabetical arrangement, but it also differs from the rest of the psalm by employing Elohim in the place of Jehovah. (Comp. Psalm 34:22.)
Verse 22. - Redeem Israel, O God, out of all his troubles. It is supposed by some that this verse was added during the "trouble" of the Captivity; and certainly its stand-lug outside the alphabetical arrangement favours this view; but the similar irregularity at the close of Psalm 34, rather makes against it. David evidently was not a slave to a mechanical arrangement; and any pious Israelite, at any age (therefore certainly David) might naturally append a prayer for his people to an outpouring of prayer for himself. Moreover, redemption is an idea familiar to David (Psalm 19:14; Psalm 26:11; Psalm 31:5; Psalm 34:22).
25:15-22 The psalmist concludes, as he began, with expressing dependence upon God, and desire toward him. It is good thus to hope, and quietly to wait for the salvation of the Lord. And if God turns to us, no matter who turns from us. He pleads his own integrity. Though guilty before God, yet, as to his enemies, he had the testimony of conscience that he had done them no wrong. God would, at length, give Israel rest from all their enemies round about. In heaven, God's Israel will be perfectly redeemed from all troubles. Blessed Saviour, thou hast graciously taught us that without thee we can do nothing. Do thou teach us how to pray, how to appear before thee in the way which thou shalt choose, and how to lift up our whole hearts and desires after thee, for thou art the Lord our righteousness.
Redeem Israel, O God, out of all his troubles. David was not only concerned for himself, but for the whole nation of Israel, which was involved in trouble through this unnatural rebellion of his son, and many of his subjects; and no doubt he may have a further view to the redemption of the church of God, the spiritual Israel, by the Messiah; and his sense may be, that God would send the promised Redeemer and Saviour, to redeem his people from all their iniquities; from the law, its curses and condemnation; to ransom them out of the hands of Satan, that is stronger than they; and to deliver them from all their enemies, and from death itself, the last enemy, which will put an end to all their troubles, Isaiah 35:10.
