Jesus calls Matthew, a tax collector, to follow him. He does.
The commentary makes a few points here which I hadn’t thought of, such as this: Matthew was probably familiar with Jesus’ ministry and was in any case ready to be called. His willingness to leave his work and join the disciple brotherhood was an indication that he had already put his affairs in order and was ready to make the move when called.
