“Be Thou exalted above the heavens, O God, and Thy glory above all the earth. That Thy beloved ones may be delivered, save Thou with Thy right hand and hearken unto me.”
…the Psalmist says, ‘Save Thou with Thy right hand…” in order, that is, to indicate, in saying, ‘right hand’ that it was eternal salvation that he sought. Hence again it is written, Your right hand, O God, dashed the enemy in pieces” (Ex. 15:7). For the enemies of God, though they prosper in His left hand, are dashed to pieces with His right, since for the most part the present life elevates the bad, but the coming of eternal blessedness condemns them.
