“Then the word of the LORD came to Jeremiah: Thus says the LORD of hosts, the God of Israel: Go and say to the people of Judah and the inhabitants of Jerusalem, Can you not learn a lesson and obey my words? Says the LORD. The command has been carried out that Jonadab son of Rechab gave to his descendants to drink no wine; and they drink none to this day, for they have obeyed their ancestor’s command. But I myself have spoken to you persistently, saying ‘Turn now everyone of you from your evil way, and amend your doings, and do not go after other gods to serve them, and then you shall live in the land that I gave to you and your ancestors.’ But you did not incline your ears or obey me. The descendants of Jonadab son of Rechab have carried out the command that their ancestor gave them, but his people has not obeyed me. Therefore, thus says the LORD, the God of hosts, the God of Israel: I am going to bring on Judah and on all the inhabitants of Jerusalem every disaster that I have pronounced against them; because I have spoken to them and they have not listened, I have called to them and they have not answered.
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 your ancestor Jonadab, and kept all his precepts, and done all that he commanded you, therefore thus says the LORD of hosts, the God of Israel: Jonadab son of Rechab shall not lack a descendant to stand before me for all time.” Jeremiah 35: 12-19
