Jeremiah 35:16-19

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

17“Therefore thus says the Lord God of hosts, the God of Israel: ‘Behold, I will bring on Judah and on all the inhabitants of Jerusalem all the doom that I have pronounced against them; because I have spoken to them but they have not heard, and I have called to them but they have not answered.’ ”

18And Jeremiah said to the house of the Rechabites, “Thus says the Lord of hosts, 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 the Lord of hosts, the God of Israel: “Jonadab the son of Rechab shall not lack a man to stand before Me forever.” ’ ”
