Maathew 9:35-38

The harvest is plentiful but the workers are few.
v.35 Jesus went throughout their towns healing the sick of all manner of disease, preaching the gospel of the kingdom, and teaching in their synagogues. This verse closely parallels 4:23.
v.36 He had compassion on the crowds because they were like sheep without a shepherd. But Jesus is shepherd to his people (Mi 5:4). Jesus perhaps refers to the Pharisees lack of pastoral care for the people of Israel.
v.37-38 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.” The harvest is the multitudes of people in need of a savior.
