And Jesus went throughout all the cities and villages, teaching in their synagogues and proclaiming the gospel of the kingdom and healing every disease and every affliction. When he saw the crowds, he had compassion for them, because they were harassed and helpless, like sheep without a shepherd. Then he said to his disciples, “The harvest is plentiful, but the laborers are few; therefore pray earnestly to the Lord of the harvest to send out laborers into his harvest.”
And he called to him his twelve disciples and gave them authority over unclean spirits, to cast them out, and to heal every disease and every affliction. The names of the twelve apostles are these: first, Simon, who is called Peter, and Andrew his brother; James the son of Zebedee, and John his brother; Philip and Bartholomew; Thomas and Matthew the tax collector; James the son of Alphaeus, and Thaddaeus; Simon the Zealot, and Judas Iscariot, who betrayed him.
These twelve Jesus sent out, instructing them, “Go nowhere among the Gentiles and enter no town of the Samaritans, but go rather to the lost sheep of the house of Israel. And proclaim as you go, saying, ‘The kingdom of heaven is at hand.’ Heal the sick, raise the dead, cleanse lepers, cast out demons. You received without paying; give without pay. Acquire no gold or silver or copper for your belts, no bag for your journey, or two tunics or sandals or a staff, for the laborer deserves his food.
(Matthew 9:35-10:10 ESV)
