Jeremiah 35:16-19

16Yes, the sons of Jonadab son of Rechab carried out their ancestor’s command he gave them, but these people have not obeyed me.

17Therefore, this is what the Lord, the God of Armies, the God of Israel, says: I will certainly bring on Judah and on 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 did not answer.’”

18But to the house of the Rechabites Jeremiah said, “This is what the Lord of Armies, the God of Israel, says: ‘Because you have obeyed the command of your ancestor Jonadab and have kept all his commands and have done everything he commanded you,

19this is what the Lord of Armies, the God of Israel, says: Jonadab son of Rechab will never fail to have a man to stand before me always.’”
