“Jesus went up
He called to him
Those whom he wanted.
They came to him.”
Καὶ ἀναβαίνει εἰς τὸ ὄρος, καὶ προσκαλεῖται οὓς ἤθελεν αὐτός, καὶ ἀπῆλθον πρὸς αὐτόν.
There is something similar in Luke, chapter 6:13, where Jesus called these special disciples, apostles. Matthew, chapter 10:1, said that Jesus gave them authority to cast out unclean spirits just as he had done. Here Mark said that Jesus went up a mountain (Καὶ ἀναβαίνει εἰς τὸ ὄρος), much like Moses. Then Jesus called the ones that he wanted or desired to be with him (καὶ προσκαλεῖται οὓς ἤθελεν αὐτός). They, of course, came to him (καὶ ἀπῆλθον πρὸς αὐτόν). The distinction was that disciples were learners or followers. The apostles, on the other hand, were to be sent out on a mission to do something.
