1) "Then he called his twelve disciples together," (sungkalesamenos de tous dodeka) "Then when he had called the twelve together," the twelve apostles, Matthew 10:1; Mark 5:7. The calling was out of a larger company, or the church-assembly of disciples who followed Him, John 15:16; John 15:27; 1 Corinthians 12:28.
2) "And gave them power and authority," (edoken autois dunamin kai eksousian) "He gave to them both dynamic power and administrative authority." The first refers to power to perform miracles and the second refers to a priority to use the powers to advance His name, 1 Corinthians 12:28.
3) "Over all devils, and to cure diseases." (epi panta ta daimonia kai nosous therapeuein) "Over all the demons and diseases, to heal," from their powers of debasement, physically, and mentally, John 20:30-31. They quelled or quieted down the demons, casting’ them from men, a thing about which they rejoiced upon their return to Jesus, Luke 10:17-20.
