'Dust' in the Bible

And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet.

And whosoever shall not receive you, nor hear you, when ye depart thence, shake off the dust under your feet for a testimony against them. Verily I say unto you, It shall be more tolerable for Sodom and Gomorrha in the day of judgment, than for that city.

And whosoever will not receive you, when ye go out of that city, shake off the very dust from your feet for a testimony against them.

Even the very dust of your city, which cleaveth on us, we do wipe off against you: notwithstanding be ye sure of this, that the kingdom of God is come nigh unto you.

But they shook off the dust of their feet against them, and came unto Iconium.

And as they cried out, and cast off their clothes, and threw dust into the air,

And they cast dust on their heads, and cried, weeping and wailing, saying, Alas, alas, that great city, wherein were made rich all that had ships in the sea by reason of her costliness! for in one hour is she made desolate.
