Origin and Application:
This expression appears in two places in the Bible. In the Gospel of Matthew, Jesus asked the disciples to shake the dust of a town off their feet if their preaching was not welcomed there. This practice was a demonstration of their separation from those who rejected the word of God. The practice of “shaking dust from one’s feet” was recorded in the Book of Acts. While Paul and Barnabas were teaching the Gentiles in Antioch, who gladly received the word of God, both of them were rejected and expelled from the region by the Jewish community. So Paul and Barnabas shook the dust off their feet in protest against them.
