John Chrysostom
"Through Him," that is, through the High Priest, in relation to the flesh. "Lips that glorify His name": he speaks as if saying, if we must confess Him, then let us say nothing blasphemous, shameful, bold, senseless, or arrogant. Rather, let us do and say everything with fear and reverence.
He says this not without cause, but because he knew their sufferings. In sufferings the soul becomes despondent and irritated. But we, he says, must not act so.
