Matthew 9:36-38

But when he saw the multitudes, he was moved with compassion on them, because they fainted, and were scattered abroad, as sheep having no shepherd. {fainted...: or, were tired and lay down} Then saith he unto his disciples, The harvest truly {is} plenteous, but the labourers {are} few; Pray ye therefore the Lord of the harvest, that he will send forth labourers into his harvest.
