The king shall joy in your strength, O LORD; and in your salvation how greatly shall he rejoice!
All Commentaries on Psalms 21:1 Go To Psalms 21
Augustine of Hippo
AD 430
2. "O Lord, the King shall rejoice in Thy strength" (ver. 1). O Lord, in Thy strength, whereby the Word was made flesh, the Man Christ Jesus shall rejoice. "And shall exult exceedingly in Thy salvation." And in that, whereby Thou quickenest all things, shall exult exceedingly.
