John 6:72

But he spake, &c. Christ forewarns the Apostles, so that when they should afterwards behold the treachery of Judas, they might know that He had foreseen and foretold it, and therefore that it was not against His will, but by the permission of His certain counsel that this was done to bring about His death, by which he might redeem the human race.

Here John finishes the acts of the second year of Christ's preaching, up to the third year, or from the second Passover to the third. He proceeds with the acts of the third year in the following chapter. He passes over therefore many acts of Christ's second year, because they had been given at length by the other three Evangelists. He concludes Christ's second year with the multiplication of the loaves, which He wrought about the time of the Passover, and which furnished the occasion of Christ's long argument with the Jews concerning the spiritual bread and His Flesh to be partaken in the Eucharist.
