Exodus 25:10-16

10And they shall make an ark of shittim wood: two cubits and a half shall be its length, and a cubit and a half its breadth, and a cubit and a half its height. 11And thou shalt overlay it with pure gold, within and without shalt thou overlay it, and shalt make upon it a crown of gold around it. 12And thou shalt cast four rings of gold for it, and put them in its four corners; and two rings shall be in its one side, and two rings in its other side. 13And thou shalt make staffs of shittim wood, and overlay them with gold. 14And thou shalt put the staffs into the rings by the sides of the ark, that the ark may be borne with them. 15The staffs shall be in the rings of the ark: they shall not be taken from it. 16And thou shalt put into the ark the testimony which I shall give thee.
