Exodus 25:14

You shall overlay it with pure gold. You shall overlay it inside and outside, and you shall make a gold molding around it.

You shall cast four rings of gold for it, and put them in its four feet. Two rings shall be on the one side of it, and two rings on the other side of it.

You shall make poles of acacia wood, and overlay them with gold.

The poles shall be in the rings of the ark. They shall not be taken from it.

You shall put the covenant which I shall give you into the ark.

You shall make a mercy seat of pure gold. Two and a half cubits shall be its length, and a cubit and a half its width.
