Jeremiah 35:18-19

But to the house of the Rechabites Jeremiah said, “Thus says the LORD of hosts, the God of Israel: Because you have obeyed the command of Jonadab your father and kept all his precepts and done all that he commanded you, therefore thus says the LORD of hosts, the God of Israel: Jonadab the son of Rechab shall never lack a man to stand before me.”
