Albert Barnes Commentary Psalms 26:7

"That I may make the voice of thanksgiving to be heard, And tell of all thy wondrous works." — Psalms 26:7 (ASV)

That I may publish with the voice of thanksgiving - literally, “that I may cause to be heard;” that is, that I may make known to others. The idea is, that he would make known to others what he had learned from God; or that He would make known to them the delights of His service, and seek to win them to His worship. This he would do with a thankful remembrance of the favors he himself had enjoyed, or as an expression of his gratitude for the mercies which had been conferred on him. As expressive of his gratitude to God, he would endeavor to win others also to His service.

And tell of all thy wondrous works - The wonderful things which you have done - your works of creation, providence, and salvation. His own mind was deeply impressed with the greatness of God’s works, and he would desire to make the divine actions known as far as possible in the world. (Psalms 66:16; Psalms 145:5–6). This is always one of the evidences of true piety. Those who have been impressed properly with a sense of the greatness and goodness of God, those who have experienced His pardoning mercy and forgiving grace, always desire to make these things known to others, and to invite them also to partake of the mercies connected with the divine favor. .
