Luke 10: 1 - 9
1 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.
2 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.
3 Go your way; behold, I send you out as lambs in the midst of wolves.
4 Carry no purse, no bag, no sandals; and salute no one on the road.
5 Whatever house you enter, first say, `Peace be to this house!'
6 And if a son of peace is there, your peace shall rest upon him; but if not, it shall return to you.
7 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.
8 Whenever you enter a town and they receive you, eat what is set before you;
9 heal the sick in it and say to them, `The kingdom of God has come near to you.'
