'Dusk' in the Bible

They are smashed to pieces from dawn to dusk;they perish forever while no one notices.

{At dusk} the murderer rises; he kills [the] needy and [the] poor, and in the night he is like a thief.

And [the] eye of [the] adulterer waits for dusk, saying, {'No eye will see me,'} and he places a covering [on his] face.
