Matthew 9:35-10:8 (ESV)
35 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. 36 When he saw the crowds, he had compassion for them, because they were harassed and helpless, like sheep without a shepherd. 37 Then he said to his disciples, “The harvest is plentiful, but the laborers are few; 38 therefore pray earnestly to the Lord of the harvest to send out laborers into his harvest.”
10:1 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. 2 The names of the twelve apostles are these… 5 These twelve Jesus sent out, instructing them, “Go… proclaim as you go, saying, ‘The kingdom of heaven is at hand.’ 8 Heal the sick, raise the dead, cleanse lepers, cast out demons. You received without paying; give without pay.”
