'Dust' in the Bible

For her blood was in the midst of her; {she put it on a bare rock}; she [did] not pour it on the ground to cover it [with] dust.

From the abundance of his horses he will cover you [with] their fine dust; at [the] sound of horseman and wheel and chariot your walls will shake, at his coming into your gates like the entrance of a city [that is] being broken through.

and they will lament over you with their voice, and they will cry out bitterly, and they will throw dust on their heads, [and] they will roll in the dust.
