I 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 ( Psalms 22:22 ) .
