my strength faileth # 19_PSA_31_10 # 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 strength faileth # 19_PSA_38_10 # My heart panteth, my strength faileth me: as for the light of mine eyes, it also is gone from me. 
my strength faileth # 19_PSA_71_09 # Cast me not off in the time of old age; forsake me not when my strength faileth.
