Exodus 25:10-16

“And they shall make an ark of acacia wood; two and a half cubits shall be its length, a cubit and a half its width, and a cubit and a half its height. And you shall overlay it with pure gold, inside and out you shall overlay it, and shall make on it a molding of gold all around. You shall cast four rings of gold for it, and put them in its four corners; two rings shall be on one side, and two rings on the other side. And you shall make poles of acacia wood, and overlay them with gold. You shall put the poles into the rings on the sides of the ark, that the ark may be carried by them. The poles shall be in the rings of the ark; they shall not be taken from it. And you shall put into the ark the Testimony which I will give you.
