Luke 10:3-7

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

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

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

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

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.
