Jeremiah 35:18-19

18 ¶ And Jeremiah said unto the house of the Rechabites, Thus saith the Lord of hosts, the God of Israel; Because ye have obeyed the commandment of Jonadab your father, and kept all his precepts, and done according unto all that he hath commanded you: 19 Therefore thus saith the Lord of hosts, the God of Israel; Jonadab the son of Rechab shall not want a man to stand before me for ever.
