Where it appears

• Mark 6:11Whoever will not receive you nor hear you, as you depart from there, shake off the dust that is under your feet for a testimony against them. Assuredly, I tell you, it will be more tolerable for Sodom and Gomorrah in the day of judgment than for that city!”
• Rev 18:19They cast dust on their heads, and cried, weeping and mourning, saying, ‘Woe, woe, the great city, in which all who had their ships in the sea were made rich by reason of her great wealth!’ For she is made desolate in one hour.
