Jeremiah 35:16-19

16Yea, the sons of Jonadab the son of Rechab have performed the commandment of their father which he commanded them, but this people hath not hearkened unto me; 17therefore thus saith Jehovah the 1God of hosts, the 2God of Israel: Behold, I will bring upon Judah and upon all the inhabitants of Jerusalem all the evil that I have pronounced against them, because I have spoken unto them, but they have not hearkened, and I have called unto them, but they have not answered. 18And Jeremiah said unto the house of the Rechabites, Thus saith Jehovah of hosts, the 3God of Israel: Because ye have obeyed the commandment of Jonadab your father, and kept all his injunctions, and have done according unto all that he hath commanded you; 19therefore thus saith Jehovah of hosts, the 4God of Israel, There shall not fail to Jonadab the son of Rechab a man to stand before me, for ever.
