Verse 14. Shake off the dust of your feet. The Jews taught uniformly that the dust of the Gentiles was impure, and was to be shaken off. To shake off the dust from the feet, therefore, was a significant act, denoting that they regarded them as impure, profane, and heathenish, and unworthy of their instruction, and that they declined all further connexion with them. It is recorded that this was actually done by some of the apostles. See Ac 13:51; 18:6.
