'Fail' in the Bible

There shall not any man be able to stand before thee all the days of thy life: as I was with Moses, so I will be with thee: I will not fail thee, nor forsake thee.

And Joshua said, Hereby ye shall know that the living God is among you, and that he will without fail drive out from before you the Canaanites, and the Hittites, and the Hivites, and the Perizzites, and the Girgashites, and the Amorites, and the Jebusites.

Now therefore ye are cursed, and there shall never fail to be of you bondmen, both hewers of wood and drawers of water for the house of my God.

As Jehovah had commanded Moses his servant, so did Moses command Joshua, and so did Joshua: he let nothing fail of all that Jehovah had commanded Moses.
