This was according to our Saviour’s command, Mat_10:14Mar_6:11Luk_9:5, so often is it mentioned, and so considerable a matter it is for us to know, and dread the punishment appointed for such as refuse the gospel, and contemn the salvation offered by it. What this was symbolical of is not expressed. The Hebrew proverb says, The dust of an ethnic city or country doth pollute a man; and they might by this represent, that the inhabitants of such a city or place, who did not entertain the gospel, and the ministers thereof, they would repute as the vilest sinners, and they should by God be dealt with accordingly.
