Jeremiah 35:16-19

16For the sons of Jonadab son of Rechab have kept the commandment of their father which he commanded them, but this people have not obeyed Me.’”

17Therefore thus says Adonai Elohei-Tzva’ot, the God of Israel: “I am about to bring on Judah and all the inhabitants of Jerusalem all the evil that I have pronounced against them, because I spoke to them but they have not heard, and I have called to them but they have not answered.”

18Now Jeremiah said to the house of the Rechabites, thus says Adonai-Tzva’ot, the God of Israel: “Because you have obeyed the commandment of Jonadab your father, and kept all his precepts, and done according to all that he commanded you,”

19therefore thus says Adonai-Tzva’ot, the God of Israel: “There will never be cut off for Jonadab son of Rechab a man to stand before Me forever.”
