'Watch' in the Bible

And the watchman gave a loud cry, O my lord, I am on the watchtower all day, and am placed in my watch every night:

Be shamed, O Zidon: for the sea, the strong place of the sea has said, I have not been with child, or given birth; I have not taken care of young men, or kept watch over the growth of virgins

And I will keep you and this town safe from the hands of the king of Assyria: and I will keep watch over this town.
