'Watchtower' in the Bible

The Israelites secretly did what was not right against the Lord their God. They built high places in all their towns from watchtower to fortified city.

He defeated the Philistines as far as Gaza and its borders, from watchtower to fortified city.

Then the lookout reported,“Lord, I stand on the watchtower all day,and I stay at my post all night.

For the palace will be forsaken,the busy city abandoned.The hill and the watchtower will becomebarren places forever,the joy of wild donkeys,and a pasture for flocks,

And you, watchtower for the flock,fortified hill of Daughter Zion,the former rule will come to you,sovereignty will come to Daughter Jerusalem.
