Jonadab in the Bible

But Amnon had a friend, whose name was Jonadab, the son of Shimeah David's brother: and Jonadab was a very subtil man.

"Why are you so depressed these past few mornings," Jonadab asked Amnon, "since you're a son of the king? Why not tell me?" Amnon replied, "I'm in love with my brother Absalom's sister Tamar."

And Jonadab said unto him, Lay thee down on thy bed, and make thyself sick: and when thy father cometh to see thee, say unto him, I pray thee, let my sister Tamar come, and give me meat, and dress the meat in my sight, that I may see it, and eat it at her hand.

And Jonadab, the son of Shimeah David's brother, answered and said, Let not my lord suppose that they have slain all the young men the king's sons; for Amnon only is dead: for by the appointment of Absalom this hath been determined from the day that he forced his sister Tamar.

And Jonadab said unto the king, Behold, the king's sons come: as thy servant said, so it is.

But they answered, "We do not drink wine because our ancestor Jonadab son of Rechab commanded us not to. He told us, 'You and your children must never drink wine.

We and our wives and our sons and daughters have obeyed everything our ancestor Jonadab commanded us. We have never drunk wine.

We have lived in tents. We have obeyed our ancestor Jonadab and done exactly as he commanded us.

Jonadab son of Rechab ordered his descendants not to drink wine. His orders have been carried out. To this day his descendants have drunk no wine because they have obeyed what their ancestor commanded them. But I have spoken to you over and over again, but you have not obeyed me!

Yes, the descendants of Jonadab son of Rechab have carried out the orders that their ancestor gave them. But you people have not obeyed me!

Then Jeremiah spoke to the Rechabite community, "The Lord God of Israel who rules over all says, 'You have obeyed the orders of your ancestor Jonadab. You have followed all his instructions. You have done exactly as he commanded you.'

So the Lord God of Israel who rules over all says, 'Jonadab son of Rechab will never lack a male descendant to serve me.'"
