'Grief' in the Bible

My eyesight has faded because of grief, it has dimmed because of all my enemies.

But you do see! You take note of trouble and grief in order to take the matter into your own hand. The helpless one commits himself to you; you have been the orphan's helper.

Be gracious to me, LORD, for I am in distress. My eyes have been consumed by my grief along with my soul and my body.
