Jesus went out to the lake with his disciples, and a large crowd followed him. They came from all over Galilee, Judea, Jerusalem, Idumea, from east of the Jordan River, and even from as far north as Tyre and Sidon. The news about his miracles had spread far and wide, and vast numbers of people came to see him. Jesus instructed his disciples to have a boat ready so the crowd would not crush him. He had healed many people that day, so all the sick people eagerly pushed forward to touch him. And whenever those possessed by evil spirits caught sight of him, the spirits would throw them to the ground in front of him shrieking, “You are the Son of God!” But Jesus sternly commanded the spirits not to reveal who he was. Afterward Jesus went up on a mountain and called out the ones he wanted to go with him. And they came to him. Then he appointed twelve of them and called them his apostles. They were to accompany him, and he would send them out to preach, giving them authority to cast out demons.
