And he had prepared for him a great chamber, where aforetime they laid the meat offerings, the frankincense, and the vessels, and the tithes of the corn, the new wine, and the oil, which was commanded...

And then he built chambers against all the house, five cubits high: and they rested on the house with timber of cedar.
