'Fail' in the Bible

Sell what ye possess and give alms; make to yourselves purses which do not grow old, a treasure which does not fail in the heavens, where thief does not draw near nor moth destroy.

But it is easier that the heaven and the earth should pass away than that one tittle of the law should fail.

but I have besought for thee that thy faith fail not; and thou, when once thou hast been restored, confirm thy brethren.
