(7) Therefore my heart greatly rejoiceth.--Better, danceth for joy, as in the Prayer Book. Another possible translation is, "And when I have been helped my heart will dance for joy."

With my song.--Literally, from my song, but the reading is doubtful. The LXX. have "my flesh has flourished," which is probably correct.

Verse 7. - The Lord is my Strength and my Shield (see Psalm 18:1, 2; Psalm 119:114). My heart trusted in him, and I am helped. As far as feeling goes, David is already "helped." He feels himself delivered out of his peril. Therefore, he says, my heart greatly rejoiceth; and with my song - literally, out of my song, which is explained to mean "out of my store of song" - will I praise him. He is ready to offer thanksgiving for a mercy not yet received.

28:6-9 Has God heard our supplications? Let us then bless his name. The Lord is my strength, to support me, and carry me on through all my services and sufferings. The heart that truly believes, shall in due time greatly rejoice: we are to expect joy and peace in believing. God shall have the praise of it: thus must we express our gratitude. The saints rejoice in others' comfort as well as their own: we have the less benefit from the light of the sun, nor from the light of God's countenance, for others' sharing therein. The psalmist concludes with a short, but comprehensive prayer. God's people are his inheritance, and precious in his eyes. He prays that God would save them; that he would bless them with all good, especially the plenty of his ordinances, which are food to the soul. And direct their actions and overrule their affairs for good. Also, lift them up for ever; not only those of that age, but his people in every age to come; lift them up as high as heaven. There, and there only, will saints be lifted up for ever, never more to sink, or be depressed. Save us, Lord Jesus, from our sins; bless us, thou Son of Abraham, with the blessing of righteousness; feed us, thou good Shepherd of the sheep, and lift us up for ever from the dust, O thou, who art the Resurrection and the Life.The Lord is my strength,.... That is, the author both of natural and spiritual strength; that gave him strength of body, and fortitude of mind, to bear up under all the exercises he was tried with; the strength of his life, spiritual and temporal, and of his salvation; the strength of his heart under present distresses, and who he knew would be so in the hour of death, when his heart and strength would fail;

and my shield; to protect and defend him; as were the love, power, and faithfulness of God, and the Lord Jesus Christ, his power and fulness, his blood, righteousness, and salvation;

my heart trusted in him; in the Lord as his strength and shield; not in any creature, nor in his own strength and righteousness; but in the Lord God, in whom are righteousness and strength: and it is plain he did not trust in his own heart, since his heart trusted in the Lord; and which shows that his trust was an hearty one, his faith was a faith unfeigned, he believed with the heart unto righteousness;

and I am helped: this was the fruit of his trust, even a gracious experience of divine assistance: saints are helpless in themselves, and are also as to the help of man; God is the only helper of them; he helps them out of all their troubles; in whatsoever he calls them unto, and to what they want; and the help he affords is sometimes quick, and always seasonable; and sometimes by means, and sometimes without them;

therefore my heart greatly rejoiceth; that is, in the Lord, the ground of which was the help he had from him; and this joy was very great, a joy unspeakable, and full of glory; it was not carnal, but spiritual, a heart joy, joy in the Holy Ghost;

and with my song will I praise him; praise is due to God, what glorifies him, and is acceptable to him; it becomes the saints, is comely for them, and it is pleasant work to them, when grace is in exercise; see Psalm 69:30; this may be understood of one of his songs, and one of the best of them, and of one better than this, as a Jewish writer (u) observes.
