Exodus 37:3

1 Bezalel made the ark of acacia wood. Two cubits and a half was its length, a cubit and a half its breadth, and a cubit and a half its height.

2 And he overlaid it with pure gold inside and outside, and made a molding of gold around it.

3 And he cast for it four rings of gold for its four feet, two rings on its one side and two rings on its other side.

4 And he made poles of acacia wood and overlaid them with gold

5 and put the poles into the rings on the sides of the ark to carry the ark.
