Thematic Bible: Heinousness of, illustrated

"But what Rechab's son Jonadab commanded his sons about not drinking wine is observed, and they haven't drunk wine until this day. Indeed, they obey the commands of their ancestor. But I've spoken to you again and again, and you haven't obeyed me. I've sent you all my servants, the prophets, sending them again and again. I've said, "Each of you turn from his evil behavior and make your deeds right. Don't follow other gods to serve them. Then you will remain in the land that I gave to you and to your ancestors.' But you haven't paid attention and you haven't obeyed me. Indeed the descendants of Rechab's son Jonadab have carried out the command of their ancestor that he gave them, but this people has not obeyed me." read more.
Therefore, this is what the LORD God of the Heavenly Armies, the God of Israel says: "Look, I'm bringing on Judah and all the residents of Jerusalem all the disaster that I pronounced against them, because I spoke to them, but they didn't listen, and I called out to them, but they didn't answer."'" Then Jeremiah told the house of the Rechabites, "This is what the LORD God of the Heavenly Armies, the God of Israel says: "Because you obeyed the commandment of your ancestor Jonadab, have observed all his commandments, and have done everything that he commanded you,' therefore, this is what the LORD God of the Heavenly Armies, the God of Israel says: "Rechab's son Jonadab won't lack a descendant who serves me always.'"
