'Ashes' in the Bible

And Jehovah said unto Moses and unto Aaron, Take to you handfuls of ashes of the furnace, and let Moses sprinkle it toward heaven in the sight of Pharaoh.

And they took ashes of the furnace, and stood before Pharaoh; and Moses sprinkled it up toward heaven; and it became a boil breaking forth with blains upon man and upon beast.

And thou shalt make its pots to take away its ashes, and its shovels, and its basins, and its flesh-hooks, and its firepans: all the vessels thereof thou shalt make of brass.
