'Fail' in the Bible

{To the chief Musician upon Sheminith, A Psalm of David.} Help, LORD; for the godly man ceaseth; for the faithful fail from among the children of men.

I am weary of my crying: my throat is dried: mine eyes fail while I wait for my God.

Is his mercy clean gone for ever? doth his promise fail for evermore?

Nevertheless my lovingkindness will I not utterly take from him, nor suffer my faithfulness to fail.

Mine eyes fail for thy word, saying, When wilt thou comfort me?

Mine eyes fail for thy salvation, and for the word of thy righteousness.
