This is further proof that Jesus is God as well as the Messiah. He tells his disciples to ask the Lord to send out harvesters and then calls the twelve apostles to fulfill that role. As well, Jesus is the good shepherd. He is moved to compassion for the lost and desires to gather them up as a shepherd does to lost sheep. Jesus is some Savior. He is everything that we need.
Matthew 9:35-10:4 (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: first, Simon, who is called Peter, and Andrew his brother; James the son of Zebedee, and John his brother; 3 Philip and Bartholomew; Thomas and Matthew the tax collector; James the son of Alphaeus, and Thaddaeus; 4 Simon the Cananaean, and Judas Iscariot, who betrayed him.
