The LORD liveth; and blessed be my rock; and let the God of my salvation be exalted.
Closing recapitulation of the whole subject.-
Verse 46. The Lord liveth; and blessed be my Rock; and let the God of my salvation be exalted. The threefold blessing answers to that in Numbers 6:24-26: an intimation of the Trinity. With "the Lord liveth," cf. 1 Timothy 6:16, "who only hath immortality" - a tacit contrast to the dead idols, which afford no safety to their votaries. Hengstenberg translates, 'exalted is my salvation-God;' saying, that if it were a wish, the Hebrew verb would have been the apocopated future.
Verse 47. It is God ... avengeth me - not private revenge. It is the will of God that the saints should glory in the avenging of their cause, as the vindication of the cause of God Himself (Luke 18:3; Luke 18:7; Revelation 6:10-11).
Verse 48. Thou hast delivered me from the violent man - an ideal representative of all his enemies, Saul especially.
Verse 49. Therefore will I give thanks unto thee, O Lord, among the heathen, The Hebrew for "give Verse 49. Therefore will I give thanks unto thee, O Lord, among the heathen, The Hebrew for "give thanks" means also 'to confess,' and is so quoted by Paul, Romans 15:9. х yaadah (H3034), whence comes towdaah (H8426), confession, or praise.] In praising men we may exceed the truth; in praising God we can never do so. Each fresh praise we bring is only a confession of what (God is; because His excellencies always surpass our praise. This passage and Deuteronomy 32:43, and Psalms 117:1, show that salvation is designed for the pagan also. 'Since the pagan are interested in that which Yahweh does by Israel, since they also belong to the auditory in which His great deeds are to be celebrated, then God must be their God, as well as God of the Jews' (Hengstenberg).
Verse 50. Great deliverance (Hebrew, salvation) giveth he to his king. The plural indicates the fullness of the salvation vouchsafed.
And to his seed for evermore - referring to the promise, 2 Samuel 7:12-13. The last promise is twice repeated in Psalms 18:16. Compare also Psalms 21:1-13; Psalms 89:1-52:respecting the favours of the Lord to the seed of David. In Psalms 2:1-12; Psalms 45:1-17; Psalms 72:1-20; Psalms 110:1-7, Messiah exclusively is brought into view; here He is presented before us only as a member of David's seed.
