Jesus calls his twelve disciples and gives them authority over unclean spirits and every disease. Matthew names them, among them Simon Peter and Andrew, James and John, Philip, Bartholomew, Thomas, Matthew the tax collector, Thaddaeus, Simon the Zealot and Judas Iscariot, who betrayed him.
He sends them first to the lost sheep of the house of Israel, not to the Gentiles or the Samaritans. They are to proclaim that the kingdom of heaven is at hand, heal, cleanse lepers and cast out demons, and give freely what they received freely. They are to take no money or extra supplies, for the worker deserves his food. If a town does not receive them, they are to shake the dust off their feet.
Jesus warns that he sends them as sheep in the midst of wolves: they will be brought before courts and governors, and the Spirit of their Father will speak through them. There will be family divisions and they will be hated because of his name, but the one who endures to the end will be saved. A disciple is not above his teacher.
Three times he tells them not to fear. They must not fear those who kill the body but the one who can destroy soul and body in hell, and the Father cares even for sparrows and has numbered the hairs of their heads. Whoever acknowledges Jesus before others will be acknowledged before the Father. Jesus says he did not come to bring peace but a sword, that whoever loves family more than him is not worthy of him, and that whoever does not take up his cross and follow him is not either; whoever loses his life for him will find it. Whoever receives a disciple receives Jesus, and whoever gives a cup of cold water to one of these little ones will not lose his reward.
