"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.' 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, 17-20

17 The seventy returned with joy, saying, "Lord, even the demons are subject to us in your name!" 18 And he said to them, "I saw Satan fall like lightning from heaven.19 Behold, I have given you authority to tread upon serpents and scorpions, and over all the power of the enemy; and nothing shall hurt you. 20 Nevertheless do not rejoice in this, that the spirits are subject to you; but rejoice that your names are written in heaven."
