'Hide Your Face' in the Bible

[To the Chief Musician. A Psalm of David.] How long will you forget me, O LORD? forever? how long will you hide your face from me?

LORD, by your favor you have made my mountain to stand strong: you did hide your face, and I was troubled.

Hide your face from my sins, and blot out all my iniquities.

You hide your face, they are troubled: you take away their breath, they die, and return to their dust.
