You have a mighty arm: strong is your hand, and high is your right hand.
All Commentaries on Psalms 89:13 Go To Psalms 89
Augustine of Hippo
AD 430
14. "Thou hast a mighty arm" (ver. 13). Let no man arrogate anything to himself. "Thou hast a mighty arm:" by Thee we were created, by Thee we have been defended. "Thou hast a mighty arm: strong be Thy hand, and high be Thy right hand."
