'Strength Fails' in the Bible

For my life is spent with sorrow, my years with sighing. My strength fails because of my iniquity. My bones are wasted away.

My heart throbs violently, my strength fails me;And as for the light of my eyes, even that has also gone from me.

For innumerable dangers surround me. My sins overtake me so I am unable to see; they outnumber the hairs of my head so my strength fails me.

Do not cast me away in the time of old age; when my strength fails do not abandon me.

The ironsmith shapes iron and uses a chisel and works it over the coals. He forms the [idol’s] core with hammers and works it with his strong arm. He also becomes hungry and his strength fails; he drinks no water and grows tired.
