Matthew 10

¹⁴ But if the people of a house or town will not welcome you or listen to you, leave it and shake its dust from your feet! ¹⁵ Yes, I tell you, it will be more tolerable on the Day of Judgment for the people of S’dom [Sodom] and ‘Amora[Gomorrah] for that town!   emphasis added

In recent years I have learned it is well for me to search for an Eastern eye view of Scripture rather than trusting these Western eyes with which I was born. Scripture was not written in the West and when we read it that way, we often miss out. 

Shake the dust from your feet. 

I’ve read some Scholars think this directive sounds harsh. 
I don’t.
I think it was life and health for the disciples and a prophetic reminder/warning to those left behind (that sounds like mercy to me).

What do you think? 

Allow me to give you some reading materials that might shed some Eastern light.
