1 Samuel 7:12

Then Samuel took a stone, and … called the name of it Eben-ezer. We saw on 1 Samuel 4:1-22 . I that the place where Israel then suffered defeat, but which now received a more happy name, was an open plain, over which the people now chased their then victorious enemies. Here, then, Samuel set up a memorial, according to Jewish custom, and called its name Help stone. In giving his reason for it, hitherto hath Jehovah helped us, there is a plain indication of the need of further assistance. There was a long struggle before them, and Jehovah, who had aided them so mightily at its beginning, would also help them unto the end. The memorial stood halfway between Mizpeh and Shen, both which names have the article in Hebrew, because one signifies the watchtower, the other the tooth. It was a steep, pointed rock, but is not mentioned elsewhere. Dent , the French for tooth, is a common name for mountains in the Alps and Pyrenees.
