Luke 10:1-6

After these things the Lord appointed seventy others also, and sent them two by two before His face into every city and place where He Himself was about to go. Then He said to them, “The harvest truly is great, but the laborers are few; therefore pray the Lord of the harvest to send out laborers into His harvest. Go your way; behold, I send you out as lambs among wolves. Carry neither money bag, knapsack, nor sandals; and greet no one along the road. But whatever house you enter, first say, ‘Peace to this house.’ And if a son of peace is there, your peace will rest on it; if not, it will return to you.
