Exodus 25:15

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.

You shall put the poles into the rings on the sides of the ark to carry the ark.

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.

You shall make two cherubim of hammered gold. You shall make them at the two ends of the mercy seat.
