Luke 10:1-6

Now after these things the Lord appointed seventy others, and sent them two and two before his face into every city and place, whither he himself was about to come. And he said unto them, 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. Go your ways; behold, I send you forth as lambs in the midst of wolves. Carry no purse, no wallet, no shoes; and salute no man on the way. And into whatsoever house ye shall enter, first say, Peace be to this house. And if a son of peace be there, your peace shall rest upon him: but if not, it shall turn to you again.
