'Failed' in the Bible

{To the chief Musician. Upon Sheminith. A Psalm of David.} Save, Jehovah, for the godly man is gone; for the faithful have failed from among the children of men.

For innumerable evils have compassed me about: mine iniquities have taken hold upon me, so that I cannot see; they are more than the hairs of my head: and my heart hath failed me.

Look on the right hand and see; there is no man that knoweth me: refuge hath failed me; no man careth for my soul.
