'Dust' in the Bible

'And whoever may not receive you nor hear your words, coming forth from that house or city, shake off the dust of your feet,

and as many as may not receive you, nor hear you, going out thence, shake off the dust that is under your feet for a testimony to them; verily I say to you, It shall be more tolerable for Sodom or Gomorrah in a day of judgment than for that city.'

and as many as may not receive you, going forth from that city, even the dust from your feet shake off, for a testimony against them.'

And the dust that hath cleaved to us, from your city, we do wipe off against you, but this know ye, that the reign of God hath come nigh to you;

and they having shaken off the dust of their feet against them, came to Iconium,

And they crying out and casting up their garments, and throwing dust into the air,

and they did cast dust upon their heads, and were crying out, weeping and sorrowing, saying, Woe, woe, the great city! in which were made rich all having ships in the sea, out of her costliness -- for in one hour was she made waste.
