(50) This verse is by many treated as a late liturgical addition to the hymn. The change to the third person is certainly somewhat suggestive of this, but by no means conclusive.

The question of the relation of the two copies of this hymn to each other is far too complicated and difficult for discussion here. Each has been again and again claimed as the original. The best explanation of the variations is that the compositions were independent copies of some original, and that the psalm, like many others, was altered in preparation for the choir use.

Verse 50. - Great deliverance giveth he to his king; literally, he magnifies salutations to his king. The primary reference seems to be to the gracious message which God sent to David by Nathan when he had brought the tabernacle into Jerusalem, and purposed to build a "house" worthy of it (see 2 Samuel 7:8-16). God had then "saluted" David as "his servant" (ver. 5), and sent him a message of the most gracious character, even promising the kingdom to him and to his seed "for ever" (vers. 13, 16). And showeth mercy to his anointed, to David. No doubt David is primarily intended, both by the "king" of the first clause, and by the "anointed" of the second; but the combination of the two, and the immediate mention of the "seed" which is to reign "for ever," carry the passage beyond the psalmist individually, and give to the conclusion of the psalm, at any rate, a semi-Messianic character. As Hengstenberg says, "Psalms of this kind are distinguished from those which may more strictly be called Messianic, only by this - that in the latter the Messiah exclusively is brought into view, while here he is presented to our notice only as a member of the seed of David" ('Commentary on the Psalms,' vol. 1. p. 324, Engl. trans.).

18:32, and the following verses, are the gifts of God to the spiritual warrior, whereby he is prepared for the contest, after the example of his victorious Leader. Learn that we must seek release being made through Christ, shall be rejected. In David the type, we behold out of trouble through Christ. The prayer put up, without reconciliation Jesus our Redeemer, conflicting with enemies, compassed with sorrows and with floods of ungodly men, enduring not only the pains of death, but the wrath of God for us; yet calling upon the Father with strong cries and tears; rescued from the grave; proceeding to reconcile, or to put under his feet all other enemies, till death, the last enemy, shall be destroyed. We should love the Lord, our Strength, and our Salvation; we should call on him in every trouble, and praise him for every deliverance; we should aim to walk with him in all righteousness and true holiness, keeping from sin. If we belong to him, he conquers and reigns for us, and we shall conquer and reign through him, and partake of the mercy of our anointed King, which is promised to all his seed for evermore. Amen.Great deliverance giveth he to his king,.... Not that is king over him; for he is King of kings and Lord of lords; but that is made king by him, as David was; who did not usurp the throne, but was anointed king by the appointment of God, and was placed by him upon the throne; to whom he gave great deliverance from his enemies, or "magnified salvations" to him; which were great in kind, and many in number; and as Christ is, whom God has set as his King on his holy hill of Sion, against whom the Heathen raged, and kings and princes set themselves; but he is delivered from them all, and saved from the power of death and the grave, and ever lives to reign over, protect, and defend his people; in 2 Samuel 22:51, it is, he is "the tower of salvation for his king", with which compare Proverbs 18:10;

and showeth mercy to his anointed, to David, and to his seed for evermore; which may be understood either of David literally, who was the Lord's anointed, and to whom God showed mercy in various instances; and then by his seed is meant the Messiah, who was of his seed according to the flesh; or of the Messiah, whose name signifies Anointed; and who is often called David, Ezekiel 34:23, Hosea 3:5; and so some of the Jewish doctors (u) from this verse prove that the name of the Messiah is David: and by his seed are meant his spiritual seed; all the elect of God, who are given him as his children, to whom he stands in the relation of the everlasting Father: and as mercy is kept with him for evermore, Psalm 89:28; so it is shown to them in regeneration, in the forgiveness of their sins, and in their everlasting salvation.
