'Watchtower' in the Bible

The Israelites said things about the Lord their God that were not right. They built high places in all their cities, from the watchtower to the fortress.

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

Then the guard cries out: "On the watchtower, O sovereign master, I stand all day long; at my post I am stationed every night.

For the fortress is neglected; the once-crowded city is abandoned. Hill and watchtower are permanently uninhabited. Wild donkeys love to go there, and flocks graze there.

As for you, watchtower for the flock, fortress of Daughter Zion -- your former dominion will be restored, the sovereignty that belongs to Daughter Jerusalem.
