'Ark of the Lord' in the Bible

Then Solomon sent for all the responsible men of Israel, all the chiefs of the tribes and the heads of families of the children of Israel, to come to Jerusalem and take the ark of the Lord's agreement up out of the town of David, which is Zion.

And the priests took the ark of the Lord's agreement and put it in its place, in the inner room of the house, in the most holy place, under the wings of the winged ones.

Then Solomon made Pharaoh's daughter come up from the town of David to the house which he had made for her; for he said, I will not have my wife living in the house of David, king of Israel, because those places where the ark of the Lord has come are holy.
