2 Chronicles 5:9-10

9Now the poles were so long that the ends of the poles extending from the Ark could be seen in front of the inner Sanctuary, though they could not be seen from outside; and they are there to this day.

10There was nothing in the Ark except the two tablets that Moses had placed there at Horeb, where Adonai made a covenant with Bnei-Yisrael when they came out of Egypt.
