What makes them think this connection is real? seems hoaky to me.
Jeremiah 35:14-16New International Version (NIV)
14 ‘Jehonadab son of Rekab ordered his descendants not to drink wine and this command has been kept. To this day they do not drink wine, because they obey their forefather’s command. But I have spoken to you again and again, yet you have not obeyed me. 15 Again and again I sent all my servants the prophets to you. They said, “Each of you must turn from your wicked ways and reform your actions; do not follow other gods to serve them. Then you will live in the land I have given to you and your ancestors.” But you have not paid attention or listened to me. 16 The descendants of Jehonadab son of Rekab have carried out the command their forefather gave them, but these people have not obeyed me.’
