'Tower' in the Bible

Lo, days are coming, an affirmation of Jehovah, And the city hath been built to Jehovah, From the tower of Hananeel to the gate of the corner.

Concerning Moab: 'Thus said Jehovah of Hosts, God of Israel: Woe unto Nebo, for it is spoiled, Put to shame, captured hath been Kiriathaim, Put to shame hath been the high tower, Yea, it hath been broken down.
