Father, glorify thy name. Then came there a voice from heaven, saying, I have both glorified it, and will glorify it again.
Father, glorify thy name - by some present testimony.
Then came there a voice from heaven, saying, I have both glorified it - referring specially to the voice from heaven at His Baptism, and again at His Transfiguration,
And will glorify it again - that is, in the yet future scenes of His still deeper necessity; although even this very promise was a present and sublime testimony, which would irradiate the clouded spirit of the Son of Man.
