79. Paul's Companions.--From the beginning it had been the wont of the preachers of Christianity not to go alone on their expeditions, but two by two. Paul improved on this practise by going generally with two companions, one of them being a younger man, who perhaps took charge of the traveling arrangements. On his first journey his comrades were Barnabas and John Mark, the nephew of Barnabas. 80. We have already seen that Barnabas may be called the discoverer of Paul; and, when they set out on this journey together, he was probably in a position to act as Paul's patron; for he enjoyed much consideration in the Christian community. Converted apparently on the day of Pentecost, he had played a leading part in the subsequent events. He was a man of high social position, a landed proprietor in the island of Cyprus; and he sacrificed all to the new movement into which he had been drawn. In the outburst of enthusiasm which led the first Christians to share their property with one another, he sold his estate and laid the money at the apostles' feet. He was constantly employed thereafter in the work of preaching, and he had so remarkable a gift of eloquence that he was called the Son of Exhortation. An incident which occurred at a later stage of this journey gives us a glimpse of the appearance of the two men. When the inhabitants of Lystra mistook them for gods, they called Barnabas Jupiter and Paul Mercury. Now, in ancient art Jupiter was always represented as a tall, majestic and benignant figure, while Mercury was the small, swift messenger of the father of gods and men. Probably it appeared, therefore, that the large, gracious, paternal Barnabas was the head and director of the expedition, while Paul, little and eager, was the subordinate. The direction in which they set out, too, was the one which Barnabas might naturally have been expected to choose. They went first to Cyprus, the island where his property had been and many of his friends still were. It lay eighty miles to the southwest of Seleucia, the seaport of Antioch, and they might reach it on the very day they left their headquarters. 81. Cyprus--Change of Name.--But, although Barnabas appeared to be the leader, the good man probably knew already that the humble words of the Baptist might be used by himself with reference to his companion, "He must increase, but I must decrease." At all events, as soon as their work began in earnest, this was shown to be the relation between them. After going through the length of the island, from east to west, evangelizing, they arrived at Paphos, its chief town, and there the problems they had come out to face met them in the most concentrated form.
