<P> Michal explored the round chamber, but failed to find the square stone in the floor that led to the caves . Michal did, however, explore the passage and find steps leading up to the surface, though the exit was blocked by a large stone (this is the entrance near the mihrab). According to the report of her findings, which Michal gave to Dayan after having been lifted back through the shaft, there are 16 steps leading down into the passage, which is 1 cubit wide, 17.37 metres (57.0 ft) and 1 metre (3 ft 3 in) high . In the round chamber, which is 12 metres (39 ft) below the entrance to the shaft, there are three stone slabs, the middle of which contains a partial inscription of Sura 2, verse 255, from the Quran, the famous Ayatul Kursi, Verse of the Throne . </P> <P> In 1981 Seev Jevin, the former director of the Israel Antiquities Authority, entered the passage after a group of Jewish settlers from Hebron had entered the chamber via the entrance near the mihrab and discovered the square stone in the round chamber that concealed the cave entrance .
