William Burkitt on John 13:31

Observe here, 1. Our blessed Lord calls his death his glory: Now is the Son of man glorified; that is, now is the time at hand when I am to die, and shall by my death finish the work of man's redemption, and thereby eminently glorify God. God the Father was eminently glorified in the obedience and sufferings of his dear and only Son. It is true that the sufferings of Christ were ignominious in themselves, yet were they the way to his own glory, and his Father's also; for by them he redeemed a lost world, trampled upon Satan, triumphed over sin; and the Father was exceedingly glorified by the Son's giving obedience to his will, and so cheerfully suffering: Now is the Son of Man glorified, and God is glorified in him.
