Peace be to this house!

After this the Lord appointed seventy others, and sent them on ahead of him, two by two, into every town and place where he himself was about to come. And he said to them, "The harvest is plentiful, but the laborers are few; pray therefore the Lord of the harvest to send out laborers into his harvest.

Go your way; behold, I send you out as lambs in the midst of wolves. 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.'

-- Luke 10: 1 - 9
