Jeremiah 35:18-19

And 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, therefore 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.” ’ ”
