3. Shaking the Dust from the Feet.—To ceremonially shake the dust from one's feet as a testimony against another was understood by the Jews to symbolize a cessation of fellowship and a renunciation of all responsibility for consequences that might follow. It became an ordinance of accusation and testimony by the Lord's instructions to His apostles as cited in the text. In the current dispensation, the Lord has similarly directed His authorized servants to so testify against those who wilfully and maliciously oppose the truth when authoritatively presented (see Doc. and Cov. 24:15; 60:15; 75:20; 84:92; 99:4). The responsibility of testifying before the Lord by this accusing symbol is so great that the means may be employed only under unusual and extreme conditions, as the Spirit of the Lord may direct.
