Verse 13. Thou hast a mighty arm, omnipotence is thine in smiting or uplifting; strong is thy hand, thy power to create and grasp is beyond conception great; and high is thy right hand -- thy skill is incomparable, thy favour ennobling, thy working glorious. The power of God so impressed the Psalmist that in many ways he repeated the same thought: and indeed the truth of God's omnipotence is so full of refreshment to gracious hearts that it cannot be too much dwelt upon, especially when viewed in connection with his mercy and truth, as in the following verse.
