John 12:30 - Matthew Poole's English Annotations on the Holy Bible

This voice came not to instruct me, I very well knew, before it came, that my Father had glorified his own name, and would do it again; it came not principally nor solely for me, but chiefly to confirm you in this great truth, that I am the Son of God, and he whom he hath sent into the world, by and in whom he designs to glorify his own great name.
