Exodus 37:4

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

3He cast four rings of gold for it in its four feet—two rings on its one side, and two rings on its other side.

4He made poles of acacia wood and overlaid them with gold.

5He put the poles into the rings on the sides of the ark, to bear the ark.

6He made a mercy seat of pure gold. Its length was two and a half cubits, and a cubit and a half its width.
