Luke 10:1-6

After this, the Lord chose seventy-two others and sent them out in pairs ahead of him into every town and place where he planned to go. He said to them, “There are a great many people to harvest, but there are only a few workers. So pray to God, who owns the harvest, that he will send more workers to help gather his harvest. Go now, but listen! I am sending you out like sheep among wolves. Don’t carry a purse, a bag, or sandals, and don’t waste time talking with people on the road. Before you go into a house, say, ‘Peace be with this house.’ If peace-loving people live there, your blessing of peace will stay with them, but if not, then your blessing will come back to you.
