John 13:31,32 - Coke's Commentary on the Holy Bible

Therefore, when he was gone out,— Our Lord's sufferings were now at hand, Judas being gone out for a band of soldiers to apprehend him. After he was departed, Jesus took occasion to meditate upon the glory which would accrue both to himself and to the Father from those sufferings, and spake of it to his disciples, John 13:31. Moreover he told them, that, having already glorified his Father by the past actions of his life, and being about to glorify him yet further by his sufferings and death, which would display his perfections, particularly his infinite love to man, in the most strikingand amiable light, he was in his turn to receive glory from the Father; meaning that, in his human nature, he was to be most gloriously exalted in dignity and power, and that his mission from the Father was immediately to be supported by irrefragable attestations. Seeing God is glorified in him, (for so ει ο Θεος εδοξασθη, should be rendered) God will also glorify him in himself, and will speedily glorify him.
