| Barnes' Notes on the Bible I will give thee thanks ... - That is, When I am delivered I will publicly express my gratitude and joy. Compare Psalm 22:25; Psalm 18:49. I will praise thee among much people - Margin, "strong." So the Hebrew. The idea here is, "strong in respect to numbers;" that is, when a large body of people should be assembled together.
Clarke's Commentary on the BibleI will give thee thanks in the great congregation - I hope to be able to attend at the tabernacle with thy followers, and there publicly express my gratitude for the deliverance thou hast given me.
Gill's Exposition of the Entire BibleI will give thee thanks in the great congregation,.... This is the resolution the psalmist came unto; the promise he made, that should he be delivered from his enemies, he would give God thanks in the most public manner; that is, he would acknowledge God to be the author of the mercy, and himself unworthy of it; and would ascribe glory, honour, blessing, and thanksgiving to him, in the midst of the church and people of God; they joining with him in it, when he should be restored to an attendance with them he before prays for; I will praise thee among much people; meaning the same as before, the people of God meeting together for solemn worship; the great congregation of all, and the much people, will be the saints in heaven, when they shall be gathered together, and sing the song of Moses and the Lamb. The words will bear to be applied to the Messiah, see Psalm 22:22.

Matthew Henry's Concise Commentary35:17-28 Though the people of God are, and study to be, quiet, yet it has been common for their enemies to devise deceitful matters against them. David prays, My soul is in danger, Lord, rescue it; it belongs to thee the Father of spirits, therefore claim thine own; it is thine, save it! Lord, be not far from me, as if I were a stranger. He who exalted the once suffering Redeemer, will appear for all his people: the roaring lion shall not destroy their souls, any more than he could that of Christ, their Surety. They trust their souls in his hands, they are one with him by faith, are precious in his sight, and shall be rescued from destruction, that they may give thanks in heaven. |
