Matthew 9:35-38

Mat 9:35 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.
Mat 9:36 When he saw the crowds, he had compassion for them, because they were harassed and helpless, like sheep without a shepherd.
Mat 9:37 Then he said to his disciples, "The harvest is plentiful, but the laborers are few;
Mat 9:38 therefore pray earnestly to the Lord of the harvest to send out laborers into his harvest."
