'Fail' in the Bible

He went out to the spring and threw the salt in. Then he said, "This is what the Lord says, 'I have purified this water. It will no longer cause death or fail to produce crops."

Know, then, that not a word the Lord spoke against the house of Ahab will fail, for the Lord has done what He promised through His servant Elijah.”

So now, bring to me all the prophets of Baal, as well as all his servants and priests. None of them must be absent, for I am offering a great sacrifice to Baal. Any of them who fail to appear will lose their lives." But Jehu was tricking them so he could destroy the servants of Baal.
