'Watch' in the Bible

He sitteth in the lurking-places of the villages; in the secret places doth he slay the innocent: his eyes watch for the wretched.

For mine enemies speak against me, and they that watch for my soul consult together,

For a thousand years, in thy sight, are as yesterday when it is past, and as a watch in the night.

I watch, and am like a sparrow alone upon the housetop.

Set a watch, O Jehovah, before my mouth; keep the door of my lips.
