'Watchtower' in the Bible

He attacked the Philistines, invading Gaza and its borders from watchtower to fortified garrison.

When the army of Judah arrived at the remotest watchtower in the wilderness, they looked around at the invasion force, and to their surprise, there were dead bodies lying all around on the ground not one had escaped!

He plowed its land and cleared it of stones. Then he planted it with the choicest vines, built a watchtower in the middle of it, and dug a wine vat in it; He expected it to produce good grapes, but it produced only wild ones."

Then the lookout shouted: "Upon a watchtower I stand, O Lord, continually by day, and I am stationed at my post throughout the night.

"For the palace will be abandoned, the noisy city deserted; the citadel and watchtower will become barren wastes forever, the delight of wild donkeys, and a pasture for flocks,

"And you, watchtower of the flock, you stronghold of the daughter of Zion, it will happen even to you: The former dominion, even the kingdom of the daughter of Jerusalem, will come.
