'Dust' in the Bible

“For her blood [that she has shed] remains in her midst;She put it on the bare rock;She did not pour it on the groundTo cover it with dust.

They will destroy the walls of Tyre and break down her towers; and I will scrape her dust and debris from her and make her as bare as [the top of] a rock.

Because of the great number of his horses, their dust will cover you; your walls [O Tyre] will shake from the noise of the horsemen and the wagons and the chariots when he enters your gates as men enter a city that is breached.

Also they will take your riches as spoil and plunder your merchandise, and tear down your walls and your pleasant houses, and throw your stones and your timber and the debris [from your city] out in the water.

And they will make their voice heard [as they wail loudly] over youAnd they will cry bitterly.They will throw dust on their heads;They will wallow in ashes.
