Jeremiah 35:18-19

But to the Rechabites Jeremiah said, This is what the Lord of armies, the God of Israel, has said: Because you have done the orders of Jonadab your father, and have kept his rules, and done everything as he gave you orders to do it; For this reason the Lord of armies, the God of Israel, has said, Jonadab, the son of Rechab, will never be without a man to take his place before me.
