Wiping dust from my feet.
You have good scriptural support for that..., as we can see here, when people reject the Word of God and accept, instead the doctrines of demons, and refuse to repent of their evil ways and teachings...
Acts 13
50 But the Jews stirred up the devout and prominent women and the chief men of the city, raised up persecution against Paul and Barnabas, and expelled them from their region.
51 But they shook off the dust from their feet against them, and came to Iconium.
52 And the disciples were filled with joy and with the Holy Spirit.

Acts 18
5 When Silas and Timothy had come from Macedonia, Paul was compelled by the Spirit, and testified to the Jews that Jesus is the Christ.
6 But when they opposed him and blasphemed, he shook his garments and said to them, “Your blood be upon your own heads; I am clean. From now on I will go to the Gentiles.”

Luke 9
4 Whatever house you enter, stay there, and from there depart.
5 And whoever will not receive you, when you go out of that city, shake off the very dust from your feet as a testimony against them.”

Luke 10
10 But whatever city you enter, and they do not receive you, go out into its streets and say,
11 ’The very dust of your city which clings to us we wipe off against you. Nevertheless know this, that the kingdom of God has come near you.’
12 But I say to you that it will be more tolerable in that Day for Sodom than for that city.

Mark 6
10 Also He said to them, “In whatever place you enter a house, stay there till you depart from that place.
11 And whoever will not receive you nor hear you, when you depart from there, shake off the dust under your feet as a testimony against them. Assuredly, I say to you, it will be more tolerable for Sodom and Gomorrah in the day of judgment than for that city!”
12 So they went out and preached that people should repent.
13 And they cast out many demons, and anointed with oil many who were sick, and healed them.

Matthew 10
12 And when you go into a household, greet it.
13 If the household is worthy, let your peace come upon it. But if it is not worthy, let your peace return to you.
14 And whoever will not receive you nor hear your words, when you depart from that house or city, shake off the dust from your feet.
15 Assuredly, I say to you, it will be more tolerable for the land of Sodom and Gomorrah in the day of judgment than for that city!
