Adam Clarke's Bible Commentary Verse 4. Thy seed will I establish for ever, and build up thy throne to all generations. - And this covenant had most incontestably Jesus Christ in view. This is the seed, or posterity, that should sit on the throne, and reign for ever and ever. David and his family are long since become extinct; none of his race has sat on the Jewish throne for more than two thousand years: but the Christ has reigned invariably since that time, and will reign till all his enemies are put under his feet; and to this the psalmist says Selah. It will be so, it is so; and it cannot be otherwise; for the Lord hath sworn that he shall have an euerlasting kingdom, as he has an everlasting priesthood.
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.
