John Gill Commentary John 18:32

"that the word of Jesus might be fulfilled, which he spake, signifying by what manner of death he should die." — John 18:32 (ASV)

That the saying of Jesus might be fulfilled That he should be delivered by the Jews to the Gentiles, to crucify him; and that he should be lifted up from the earth, and as the serpent upon the pole: which he spoke, signifying what death he should die ; (Matthew 20:19) (John 12:32John 12:33) (3:14) and which was brought about this way, by the providence of God conducting this whole affair; and was cheerfully submitted to by Christ, in great love to his people, to redeem them from the curse of the law, being hereby made a curse for them.
