'Dust' in the Bible

and your sin, which ye have made -- the calf -- I have taken, and I burn it with fire, and beat it, grinding well till that it is small as dust, and I cast its dust unto the brook which is going down out of the mount.

Jehovah giveth the rain of thy land -- dust and ashes; from the heavens it cometh down on thee till thou art destroyed.

Exhausted by famine, And consumed by heat, and bitter destruction. And the teeth of beasts I send upon them, With poison of fearful things of the dust.
