'Dust' in the Bible

For the blood she shed is still within her.She put it out on the bare rock;she didn’t pour it on the groundto cover it with dust.

His horses will be so numerous that their dust will cover you. When he enters your gates as an army entering a breached city, your walls will shake from the noise of cavalry, wagons, and chariots.

They raise their voices over youand cry out bitterly.They throw dust on their heads;they roll in ashes.
