Jesus sends out the apostles (Mk 6:7-6:7)

“Jesus called

The twelve.

He began

To send them out

Two by two.

He gave them authority

Over the unclean spirits.”

 

Καὶ προσκαλεῖται τοὺς δώδεκα, καὶ ἤρξατο αὐτοὺς ἀποστέλλειν δύο, καὶ ἐδίδου αὐτοῖς ἐξουσίαν τῶν πνευμάτων τῶν ἀκαθάρτων,

 

This section about the authority and mission of the 12 disciples or apostles is similar to Matthew, chapter 10:1 and Luke, chapter 9:1.  Mark said that Jesus summoned or called (Καὶ προσκαλεῖται) his 12 apostles (τοὺς δώδεκα).  He began to send them out two by two (καὶ ἤρξατο αὐτοὺς ἀποστέλλειν δύο δύο).  He gave them authority over unclean or impure spirits (καὶ ἐδίδου αὐτοῖς ἐξουσίαν τῶν πνευμάτων τῶν ἀκαθάρτων).  Thus, they could cast out or banish these evil spirits or demons, but there was no mention of curing diseases, illnesses, sicknesses, or weakness, just casting out the evil spirits that might have been the cause of their illnesses.  Jesus was giving his own power or authority to cast out evil spirits to these 12 apostles.  This was a big deal.  The number 12 corresponded to the number of sons of Jacob or the 12 tribes of Israel.  Jesus thus established these 12 apostles to carry on his work in casting out evil spirits.
