'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. My strength fails me. As for the light of my eyes, it has also left me.

Don't reject me in my old age. Don't forsake me when my strength fails.

My flesh and my heart fails, but God is the strength of my heart and my portion forever.

Hurry to answer me, Yahweh. My spirit fails. Don't hide your face from me, so that I don't become like those who go down into the pit.
