Jeremiah 35:6 New International Version (NIV)

⁶ But they replied, “We do not drink wine, because our forefather Jehonadab^[a] son of Rekab gave us this command: ‘Neither you nor your descendants must ever drink wine.

Jeremiah 35:14-19 New 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.’

¹⁷ “Therefore this is what the Lord God Almighty, the God of Israel, says: ‘Listen! I am going to bring on Judah and on everyone living in Jerusalem every disaster I pronounced against them. I spoke to them, but they did not listen; I called to them, but they did not answer.’”

¹⁸ Then Jeremiah said to the family of the Rekabites, “This is what the Lord Almighty, the God of Israel, says: ‘You have obeyed the command of your forefather Jehonadab and have followed all his instructions and have done everything he ordered.’ ¹⁹ Therefore this is what the Lord Almighty, the God of Israel, says: ‘Jehonadab son of Rekab will never fail to have a descendant to serve me.’”
