Matthew 9:35-38 (NKJV)
35 Then Jesus went about all the cities and villages, teaching in their synagogues, preaching the gospel of the kingdom, and healing every sickness and every disease among the people.
36 But when He saw the multitudes, He was moved with compassion for them, because they were weary and scattered, like sheep having no shepherd.
37 Then He said to His disciples, “The harvest truly is plentiful, but the laborers are few.
38 Therefore pray the Lord of the harvest to send out laborers into His harvest.”
