Thematic Bible: Heinousness of, illustrated

Jonadab, Rechab's son, ordered his descendants not to drink wine. This order has been carried out. His descendants have not drunk any wine to this day, because they have obeyed their ancestor's order. I have spoken to you again and again, but you have refused to listen to me. I have sent all my servants the prophets to you again and again. They said: Turn from your evil ways, do what is right, and do not follow other gods in order to serve them. Then you will live in the land that I gave you and your ancestors. However, you refused to listen to me or obey me. The descendants of Jonadab, Rechab's son, have carried out the orders of their ancestor, but you refuse to listen to me.' read more.
This is what Jehovah of Hosts, the God of Israel, says: 'I am going to bring on Judah and on all those who live in Jerusalem all the disasters that I threatened. I have spoken to them, but they did not listen. I called to them, but they did not answer.' Then Jeremiah said to the family of Rechab: This is what Jehovah of Hosts, the God of Israel, says: 'You obeyed the order of your ancestor Jonadab, followed all his instructions, and did exactly what he told you to do. So this is what Jehovah of Hosts, the God of Israel, says: A descendant of Jonadab, Rechab's son, will always serve me.'
