Most of the twelve men had been called before, and had been for some time with Jesus. Others were new men whom Jesus called now for the first time. Their names are arranged in pairs, two of them together. They were Simon Peter and Andrew his brother; James and John, the sons of Zebedee; Philip and his friend Bartholomew, also called Nathanael; Thomas and Matthew, who had been the tax-gatherer; James the son of Alphaeus; another Simon, who was called "the Zealot," and Judas Iscariot, the one who afterward became the traitor and sold his Lord to his enemies. About most of these men we know very little, but some of them in later years did a great work for the church of Christ. Simon Peter was always a leader among the Twelve, being a man of quick mind and ready words; and John long after that time wrote "The Gospel according to John," one of the most wonderful books in the world. [Illustration: Kurn Hattin, where Jesus preached the Sermon on the Mount.] [Illustration: In the morning he called forth out of the vast company of people before him twelve men.] In the sight of all the people Jesus called these men to stand by his side. Then he came down from the mountain-top to the hollow place between the two summits. He sat down, with his twelve chosen men around him, and beyond this a great crowd of people. To the Twelve and to the listening multitude Jesus preached that great sermon which is called "The Sermon on the Mount." Matthew wrote it down, and you can read it in his gospel, the first book of the New Testament, in the fifth, sixth and seventh chapters. How fortunate it was that Jesus called the tax-gatherer to be one of his disciples, a man who could remember and write this great sermon for all the world to read! We give here only a few parts from this Sermon on the Mount. Jesus began with words of comfort to his followers: "Blessed are the poor in spirit; for theirs is the kingdom of heaven. Blessed are they that mourn; for they shall be comforted. Blessed are the meek; for they shall inherit the earth. Blessed are they that hunger and thirst after righteousness; for they shall be filled. Blessed are the merciful; for they shall obtain mercy. Blessed are the pure in heart; for they shall see God. Blessed are the peacemakers; for they shall be called sons of God. Blessed are they that have been persecuted for righteousness' sake; for theirs is the kingdom of heaven." Then he spoke to his disciples of what they were to be among men: "You are the salt of the earth; but if the salt have lost its savor, wherewith shall it be salted? It is thenceforth good for nothing, but to be cast out and trodden under foot of men." He went on, perhaps pointing to a town not far away, built on the top of a hill and seen everywhere around:
