A part of Jerusalem, first mentioned in 2 Chronicles 27:3, where it is said that Jotham built much “on the wall of Ophel.” Manasseh in his building, “compassed about Ophel and raised it up a very great height” (2 Chron. 33:14). On the return from exile the Nethinim dwelt there (Neh. 3:26-27; Neh. 11:21). It is supposed to have been at the S.E. corner of Jerusalem, outside the present walls, near the Virgin’s fountain. The same word is translated “tower” in 2 Kings 5:24, as in the margin of some of the above passages.
