Siloam, Tower, in
Smith’s Bible Dictionary · William Smith, F. N. Peloubet, M. A. Peloubet
(Luke 13:4) Of this we know nothing definitely beyond these words of the Lord. In connection with Ophel, there is mention made of "a tower that lieth out ," (Nehemiah 3:26) and there is no unlikelihood in connecting this projecting tower with the tower in Siloam, while one may be almost excused for the conjecture that its projection was the cause of its ultimate fall.
