Matthew 9:35-38

And Jesus went about all the cities and the villages, teaching in their synagogues, and preaching the gospel of the kingdom, and healing all manner of disease and all manner of sickness. But when he saw the multitudes, he was moved with compassion for them, because they were distressed and scattered, as sheep not having a shepherd. Then saith he unto his disciples, The harvest indeed is plenteous, but the laborers are few. Pray ye therefore the Lord of the harvest, that he send forth laborers into his harvest.
