Mark 3:15

And to have power to heal sicknesses
All manner of corporeal diseases that attend men and women:

and to cast out devils;
from such who were possessed with them: that is, he chose and appointed them to be his apostles, with a view of conferring such powers upon them hereafter; for as yet, they were not vested with them, nor sent out to exercise them; no, not till near twelve months after.
