'Dust' in the Bible

For her blood is in the midst of her; she set it upon the top of a rock; she poured it not upon the ground, to cover it with dust;

And they shall destroy the walls of Tyrus, and break down her towers: I will also scrape her dust from her, and make her like the top of a rock.

By reason of the abundance of his horses their dust shall cover thee: thy walls shall shake at the noise of the horsemen, and of the wheels, and of the chariots, when he shall enter into thy gates, as men enter into a city wherein is made a breach.

And they shall make a spoil of thy riches, and make a prey of thy merchandise: and they shall break down thy walls, and destroy thy pleasant houses: and they shall lay thy stones and thy timber and thy dust in the midst of the water.

And shall cause their voice to be heard against thee, and shall cry bitterly, and shall cast up dust upon their heads, they shall wallow themselves in the ashes:

By all your sin, even by your evil trading, you have made your holy places unclean; so I will make a fire come out from you, it will make a meal of you, and I will make you as dust on the earth before the eyes of all who see you.
