Luke 10:6 (KJV)

After these things the LORD appointed other seventy also, and sent them two and two before his face into every city and place, whither he himself would come.

Therefore said he unto them, The harvest truly is great, but the labourers are few: pray ye therefore the Lord of the harvest, that he would send forth labourers into his harvest.

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 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.

And into whatsoever city ye enter, and they receive you, eat such things as are set before you:

And heal the sick that are therein, and say unto them, The kingdom of God is come nigh unto you.

But into whatsoever city ye enter, and they receive you not, go your ways out into the streets of the same, and say,

Even the very dust of your city, which cleaveth on us, we do wipe off against you: notwithstanding be ye sure of this, that the kingdom of God is come nigh unto you.
