'Dust' in the Bible

As for your sinful thing that you had made, the calf, I took it, melted it down, ground it up until it was as fine as dust, and tossed the dust into the stream that flows down the mountain.

The Lord will make the rain of your land powder and dust; it will come down on you from the sky until you are destroyed.

They will be starved by famine, eaten by plague, and bitterly stung; I will send the teeth of wild animals against them, along with the poison of creatures that crawl in the dust.
