'Watchtower' in the Bible

The sons of Israel did things secretly which were not right against the Lord their God. Moreover, they built for themselves high places in all their towns, from watchtower to fortified city.

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

Then the lookout called,“O Lord, I stand continually by day on the watchtower,And I am stationed every night at my guard post.

Because the palace has been abandoned, the populated city forsaken.Hill and watch-tower have become caves forever,A delight for wild donkeys, a pasture for flocks;
