Matthew 10 New International Version (NIV)
Jesus Sends Out the Twelve
10 Jesus called his twelve disciples to him and gave them authority to drive out impure spirits and to heal every disease and sickness.
2 These are the names of the twelve apostles: first, Simon (who is called Peter) and his brother Andrew; James son of Zebedee, and his brother John; 3 Philip and Bartholomew; Thomas and Matthew the tax collector; James son of Alphaeus, and Thaddaeus; 4 Simon the Zealot and Judas Iscariot, who betrayed him.
5 These twelve Jesus sent out with the following instructions: “Do not go among the Gentiles or enter any town of the Samaritans. 6 Go rather to the lost sheep of Israel. 7 As you go, proclaim this message: ‘The kingdom of heaven has come near.’ 8 Heal the sick, raise the dead, cleanse those who have leprosy,[a] drive out demons. Freely you have received; freely give.
Jesus gave his disciple specific instructions that remain true to this day; check out this video from Rabbi Schneider on how to exercise authority through Jesus.
