Mark 3:7-19 NASB
Jesus withdrew to the sea with His disciples; and a great multitude from Galilee followed; and also from Judea, and from Jerusalem, and from Idumea, and beyond the Jordan, and the vicinity of Tyre and Sidon, a great number of people heard of all that He was doing and came to Him. And He told His disciples that a boat should stand ready for Him because of the crowd, so that they would not crowd Him; for He had healed many, with the result that all those who had afflictions pressed around Him in order to touch Him. Whenever the unclean spirits saw Him, they would fall down before Him and shout, “You are the Son of God!” And He earnestly warned them not to tell who He was.
And He *went up on the mountain and *summoned those whom He Himself wanted, and they came to Him. And He appointed twelve, so that they would be with Him and that He could send them out to preach, and to have authority to cast out the demons. And He appointed the twelve: Simon (to whom He gave the name Peter), and James, the son of Zebedee, and John the brother of James (to them He gave the name Boanerges, which means, “Sons of Thunder”); and Andrew, and Philip, and Bartholomew, and Matthew, and Thomas, and James the son of Alphaeus, and Thaddaeus, and Simon the Zealot; and Judas Iscariot, who betrayed Him.
