'Complaint' in the Bible

Count not thine handmaid for a daughter of Belial: for out of the abundance of my complaint and grief have I spoken hitherto.

When I say, My bed shall comfort me, my couch shall ease my complaint;

If I say, I will forget my complaint, I will leave off my heaviness, and comfort myself:

My soul is weary of my life; I will leave my complaint upon myself; I will speak in the bitterness of my soul.

As for me, is my complaint to man? and if it were so, why should not my spirit be troubled?

Even to day is my complaint bitter: my stroke is heavier than my groaning.

Attend unto me, and hear me: I mourn in my complaint, and make a noise;

{A Prayer of the afflicted, when he is overwhelmed, and poureth out his complaint before the LORD.} Hear my prayer, O LORD, and let my cry come unto thee.

I poured out my complaint before him; I shewed before him my trouble.
