Matthew 9:35-38

9:35 Then Jesus went throughout all the towns and villages, teaching in their synagogues, preaching the good news of the kingdom, and healing every kind of disease and sickness. 
9:36 When he saw the crowds, he had compassion on them because they were bewildered and helpless, like sheep without a shepherd.
9:37 Then he said to his disciples, “The harvest is plentiful, but the workers are few.
9:38 Therefore ask the Lord of the harvest to send out workers into his harvest.”
