'Dust' in the Bible

And I took your sin, the calf which ye had made, and burned it with fire, and crushed it, and ground it very small, until it became fine dust; and I cast the dust thereof into the brook that flowed down from the mountain.

Jehovah will give as the rain of thy land powder and dust; from the heavens shall it come down upon thee until thou be destroyed.

They shall be consumed with hunger, and devoured with burning heat, And with poisonous pestilence; And the teeth of beasts will I send against them, With the poison of what crawleth in the dust.
