Adam Clarke's Bible Commentary Verse 4. The king's strength ] If this Psalm were written by David, he must mean by it that he was God's vicegerent or deputy, and that, even as king, God was his strength, and the pattern according to which equity, judgment, and righteousness should be executed in Jacob.
Matthew Henry Commentary
Verses 1-5 - God governs the world by his providence, governs the church by his grace, and both by his Son. The inhabitants of the earth have cause to tremble, but the Redeemer still waits to be gracious. Let all who hear take warning, and seek his mercy. The more we humble ourselves befor God, the more we exalt him; and let us be thus reverent, for he is holy.
