Luke 10:1-6 NKJV

1 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.
2 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.
3 Go your way; behold, I send you out as lambs among wolves.
4 Carry neither money bag, knapsack, nor sandals; and greet no one along the road.
5 But whatever house you enter, first say, 'Peace to this house.'
6 And if a son of peace is there, your peace will rest on it; if not, it will return to you.
