Jeremiah 35:16-19

16Yes, the sons of Jonadab son of Rechab carried out the command their forefather gave them, but these people have not listened to Me.

17Therefore this is what the LORD God of Hosts, the God of Israel, says: ‘Behold, I will bring to Judah and to all the residents of Jerusalem all the disaster I have pronounced against them, because I have spoken to them but they have not obeyed, and I have called to them but they have not answered.’”

18Then Jeremiah said to the house of the Rechabites: “This is what the LORD of Hosts, the God of Israel, says: ‘Because you have obeyed the command of your forefather Jonadab and have kept all his commandments and have done all that he charged you to do, 19this is what the LORD of Hosts, the God of Israel, says: Jonadab son of Rechab will never fail to have a man to stand before Me.’”
