ἐκλείπω

And as a vesture shalt thou fold them up, and they shall be changed: but thou art the same, and thy years shall not fail.

And I say unto you, Make to yourselves friends of the mammon of unrighteousness; that, when ye fail, they may receive you into everlasting habitations.

But I have prayed for thee, that thy faith fail not: and when thou art converted, strengthen thy brethren.
