Luke 10:5

3 Go your ways: behold, I send you forth as lambs among wolves.

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

5 And into whatsoever house ye enter, first say, Peace to this house.

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

7 And in the same house remain, eating and drinking such things as they give: for the labourer is worthy of his hire. Go not from house to house.
