"The harvest is plentiful,
but the laborers are few;
pray therefore the Lord of the harvest
to send out laborers into his harvest."
Carry no purse, no bag, no sandals; and salute no one on the road. Whatever house you enter, first say, `Peace be to this house!' And if a son of peace is there, your peace shall rest upon him; but if not, it shall return to you. And remain in the same house, eating and drinking what they provide, for the laborer deserves his wages; do not go from house to house.
Whenever you enter a town and they receive you, eat what is set before you; heal the sick in it and say to them, `The kingdom of God has come near to you.' But whenever you enter a town and they do not receive you, go into its streets and say, `Even the dust of your town that clings to our feet, we wipe off against you; nevertheless know this, that the kingdom of God has come near.' I tell you, it shall be more tolerable on that day for Sodom than for that town.
Luke 10: 1 - 12
