'Mourning' in the Bible

You have turned my mourning into dancing for me. You have removed my sackcloth, and clothed me with gladness,

I behaved myself as though it had been my friend or my brother. I bowed down mourning, as one who mourns his mother.

I am pained and bowed down greatly. I go mourning all day long.

I will ask God, my rock, "Why have you forgotten me? Why do I go mourning because of the oppression of the enemy?"

For you are the God of my strength. Why have you rejected me? Why do I go mourning because of the oppression of the enemy?
