'Dust' in the Bible

And the LORD said unto Moses, Say unto Aaron, Stretch out thy rod, and smite the dust of the land, that it may become lice throughout all the land of Egypt.

And they did so; for Aaron stretched out his hand with his rod, and smote the dust of the earth, and it became lice in man, and in beast; all the dust of the land became lice throughout all the land of Egypt.

And the Lord said to Moses and to Aaron, Take in your hand a little dust from the fire and let Moses send it in a shower up to heaven before the eyes of Pharaoh.

And it shall become small dust in all the land of Egypt, and shall be a boil breaking forth with blains upon man, and upon beast, throughout all the land of Egypt.

So they took some dust from the fire, and placing themselves before Pharaoh, Moses sent it out in a shower up to heaven; and it became a skin-disease bursting out on man and on beast.

And make all its vessels, the baskets for taking away the dust of the fire, the spades and basins and meat-hooks and fire-trays, of brass.
