'Tower' in the Bible

O Lord, my strength and my strong tower, my safe place in the day of trouble, the nations will come to you from the ends of the earth, and say, The heritage of our fathers is nothing but deceit, even false things in which there is no profit.

See, the days are coming, says the Lord, for the building of the Lord's town, from the tower of Hananel to the doorway of the angle.
