Exodus 37:8 (KJV)

And he cast for it four rings of gold, to be set by the four corners of it; even two rings upon the one side of it, and two rings upon the other side of it.

And he made staves of shittim wood, and overlaid them with gold.

And he put the staves into the rings by the sides of the ark, to bear the ark.

And he made the mercy seat of pure gold: two cubits and a half was the length thereof, and one cubit and a half the breadth thereof.

And he made two cherubims of gold, beaten out of one piece made he them, on the two ends of the mercy seat;

And the cherubims spread out their wings on high, and covered with their wings over the mercy seat, with their faces one to another; even to the mercy seatward were the faces of the cherubims.

And he made the table of shittim wood: two cubits was the length thereof, and a cubit the breadth thereof, and a cubit and a half the height thereof:

And he overlaid it with pure gold, and made thereunto a crown of gold round about.

Also he made thereunto a border of an handbreadth round about; and made a crown of gold for the border thereof round about.

And he cast for it four rings of gold, and put the rings upon the four corners that were in the four feet thereof.
