'Fail' in the Bible

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

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.
