2 Chronicles 5:2-10

Then Solomon assembled the elders of Israel and all the heads of the tribes, the leaders of the fathers’ households of the Israelites, in Jerusalem to bring the ark of the covenant of the LORD up from the City of David, which is Zion. All the men of Israel gathered before the king at the feast in the seventh month. And all the elders of Israel came, and the Levites took up the ark. The Levitical priests brought up the ark, the Tent of Meeting, and all the holy utensils that were in the Tent. And King Solomon and all the assembly of Israel who gathered together with him before the ark were sacrificing so many sheep and oxen that they could not be counted or numbered. Then the priests brought the ark of the covenant of the LORD to its place, to the inner sanctuary of the house, into the Holy of Holies, under the wings of the cherubim; for the cherubim spread out their wings over the place of the ark, making a covering above the ark and its carrying poles. The 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. There 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.
