2 Chronicles 5:9-10

9The poles were so long that the ends of the poles of the ark were visible from the front of the Holy of Holies (inner sanctuary), but were not visible from the outside. They are there to this day.

10There was nothing in the ark except the two tablets [of the Ten Commandments] which Moses put there at Mount Horeb, when the Lord made a covenant with the Israelites, when they came out of Egypt.
