Jeremiah 35:18, 19
Then 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, / this 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.’”
