Adam Clarke's Bible Commentary Verse 5. The heavens shall praise thy wonders ] The works that shall be wrought by this descendant of David shall be so plainly miraculous as shall prove their origin to be Divine: and both saints and angels shall join to celebrate his praises.
Thy faithfulness also ] All thy promises shall be fulfilled; and particularly and supereminently those which respect the congregation of the saints-the assemblies of Christian believers.
Matthew Henry Commentary
Verses 5-14 - The more God's works are known, the more they are admired. And to praise the Lord, is to acknowledge him to be such a one that there is none like him. Surely then we should feel and express reverence when we worship God. But how little of this appears in our congregations, an how much cause have we to humble ourselves on this account! Tha almighty power which smote Egypt, will scatter the enemies of the church, while all who trust in God's mercy will rejoice in his name for mercy and truth direct all he does. His counsels from eternity, an their consequences to eternity, are all justice and judgment.
