'Strength Faileth' in the Bible

For my life is spent with grief, and my years with sighing: my strength faileth because of mine iniquity, and my bones are consumed.

My heart panteth, my strength faileth me: as for the light of mine eyes, it also is gone from me.

Cast me not off in the time of old age; forsake me not when my strength faileth.

The smith with the tongs both worketh in the coals, and fashioneth it with hammers, and worketh it with the strength of his arms: yea, he is hungry, and his strength faileth: he drinketh no water, and is faint.
