'Fail' in the Bible

that Jehovah may confirm his word which he spoke concerning me, saying, If thy sons take heed to their way, to walk before me in truth with all their heart and with all their soul, there shall not fail thee, said he, a man upon the throne of Israel.

And now, Jehovah, God of Israel, keep with thy servant David my father that which thou hast promised him, saying, There shall not fail thee a man in my sight to sit on the throne of Israel, if only thy sons take heed to their way, to walk before me as thou hast walked before me.

then will I establish the throne of thy kingdom over Israel for ever, as I promised to David thy father, saying, There shall not fail thee a man upon the throne of Israel.

For thus saith Jehovah the God of Israel: The meal in the barrel shall not waste, neither shall the oil in the cruse fail, until the day that Jehovah sendeth rain upon the face of the earth!

The meal in the barrel did not waste, neither did the oil in the cruse fail, according to the word of Jehovah which he had spoken through Elijah.
