Luke 10:1-6

1 And after these things, the Lord appointed also other seventy-two. And he sent them two and two before his face into every city and place whither he himself was to come.

2 And he said to them: The harvest indeed is great, but the labourers are few. Pray ye therefore the Lord of the harvest that he send labourers into his harvest.

3 Go: Behold I send you as lambs among wolves.

4 Carry neither purse, nor scrip, nor shoes: and salute no man by the way.

5 Into whatever house you enter, first say: Peace be to this house.

6 And if the son of peace be there, your peace shall rest upon him: but if not, it shall return to you.
