Bede the Venerable — as excerpted in the Catena Aurea on Luke 9:46-50

“Or, because they saw Peter, James, and John, taken apart to the mount, and the keys of the kingdom of heaven promised to Peter, they were angry that these three, or Peter, should have precedence over all; or because in the payment of the tribute they saw Peter made equal to the Lord, they supposed he was to be placed before the rest. But the attentive reader will find that the question was raised among them before the payment of the penny. For in truth Matthew relates that this took place at Capernaum; but Mark says, And he came to Capernaum, and being in the house, he asked them, What was it that ye disputed among yourselves in the way? But they held their peace; for by the way they had disputed among themselves who should be the greatest. (Mat. 18:24, Mark 9:33.)”
