1 Kings 5:17

Great stones. These stones were large and carefully hewn. Much labor was spent in preparing them and transporting them from the quarry to the site of the Temple in Jerusalem. They may have been employed not so much for the foundation of the Temple itself as for the substructure of the Temple area, formed into a square on the irregular summit of Mt. Moriah. In this substructure vast stones are still to be seen, which until recently were thought to date from the age of Solomon, but are now known to go back no further than Herodian times. Some of these stones are 30 ft. long and 7 1/2 ft. high.
