Help us, O God of our salvation, for the glory of thy name: and deliver us, and purge away our sins, for thy name's sake.
Purge away our sins - or 'pardon' them (Psalms 65:3.)
For the glory of thy name ... for thy name's sake - i:e., for the sake of thy glory set forth in former manifestations of thy power and goodness (Psalms 23:3; Psalms 29:1-2), Let the pagan see that this glory was justly ascribed to thee.
