Luke 10:1, 9, 11

Now after these things the Lord appointed seventy others, and sent them two and two before his face into every city and place, whither he himself was about to come.

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

Even the dust from your city, that cleaveth to our feet, we wipe off against you: nevertheless know this, that the kingdom of God is come nigh.
