Of His Paying the Tribute Money Out of the Mouth of the Fish, an Incident Which Matthew Alone Mentions
118 Matthew continues in these terms: “And when they had come to Capharnaum, they that received tribute money came to Peter, and said to him, Does not your master pay tribute? He says, Yes;” and so on, down to where we read: “You shall find a piece of money: that take, and give unto them for me and you.” He is the only one who relates this occurrence, after the interposition of which he follows again the order which is pursued also by Mark and Luke in company with him.
