The defensive walls of a city necessarily had gates for those coming and going; gates were subject to enemy assault and were therefore also specially defended (2 Chron. 26: 9). Even so an enemy might destroy the gate (Judg. 9: 49, 52). Several of the gates of Jerusalem are mentioned in the account of the rebuilding of the city by Nehemiah. In the NT the Beautiful Gate of the Temple is mentioned in Acts 3: 2.
