The Vulgate Latin, Syriac, and Arabic versions read, "a thought entered into them"; suggested very likely by Satan, which broke out into words, and issued in a warm dispute among them; and this was in the way, as they were travelling from Caesarea Philippi, to Capernaum; see ( Mark 9:33 ) .
Which of them should be greatest;
that is, "in the kingdom of heaven", as in ( Matthew 18:1 ) in the kingdom of the Messiah, which they expected would be a temporal one: wherefore the dispute was not about degrees in glory, nor in grace; nor who should be the greatest apostle and preacher of the Gospel; but who should be prime minister to the king Messiah, when he should set up his monarchy in all its grandeur and glory.
