'Dust' in the Bible

And the Lord said to Moses, Say to Aaron, Let your rod be stretched out over the dust of the earth so that it may become insects through all the land of Egypt.

And they did so; and Aaron, stretching out the rod in his hand, gave a touch to the dust of the earth, and insects came on man and on beast; all the dust of the earth was changed into insects through 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 will become small dust over all the land of Egypt, and will be a skin-disease bursting out in wounds on man and beast through 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.
