'Dust' in the Bible

And I took your sin, the image which you had made, and put it in the fire and had it hammered and crushed very small till it was only dust: and the dust I put in the stream flowing down from the mountain.

The Lord will make the rain of your land powder and dust, sending it down on you from heaven till your destruction is complete.

They will be wasted from need of food, and overcome by burning heat and bitter destruction; and the teeth of beasts I will send on them, with the poison of the worms of the dust.
