'Grief' in the Bible

My eyes are swollen from grief;they grow old because of all my enemies.

But You Yourself have seen trouble and grief,observing it in order to take the matter into Your hands.The helpless entrusts himself to You;You are a helper of the fatherless.

Indeed, my life is consumed with griefand my years with groaning;my strength has failedbecause of my sinfulness,and my bones waste away.

I went about grieving as if for my friend or brother;I was bowed down with grief,like one mourning a mother.

I am weary from grief;strengthen me through Your word.
