'Bitterness' in the Bible

Therefore I will not refrain my mouth; I will speak in the anguish of my spirit; I will complain in the bitterness of my soul.

He will not suffer me to take my breath, But filleth me with bitterness.

My soul is weary of my life; I will give free course to my complaint; I will speak in the bitterness of my soul.

And another dieth in bitterness of soul, And never tasteth of good.
