2 Kings 10:15

10:15 When he left there, he met Jehonadab, son of Rekab, who had been looking for him. Jehu greeted him and asked, “Are you as committed to me as I am to you?” Jehonadab answered, “I am!” Jehu replied, “If so, give me your hand.” So he offered his hand and Jehu pulled him up into the chariot.

Jeremiah 35:2-8

35:2 “Go to the Rechabite community. Invite them to come into one of the side rooms of the Lord’s temple and offer them some wine to drink.” 35:3 So I went and got Jaazaniah son of Jeremiah the grandson of Habazziniah, his brothers, all his sons, and all the rest of the Rechabite community. 35:4 I took them to the Lord’s temple. I took them into the room where the disciples of the prophet Hanan son of Igdaliah stayed. That room was next to the one where the temple officers stayed and above the room where Maaseiah son of Shallum, one of the doorkeepers of the temple, stayed. 35:5 Then I set cups and pitchers full of wine in front of the members of the Rechabite community and said to them, “Have some wine.” 35:6 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. 35:7 Do not build houses. Do not plant crops. Do not plant a vineyard or own one. Live in tents all your lives. If you do these things you will live a long time in the land that you wander about on.’ 35:8 We and our wives and our sons and daughters have obeyed everything our ancestor Jonadab commanded us. We have never drunk wine.

Jeremiah 35:19

35:19 So the Lord God of Israel who rules over all says, ‘Jonadab son of Rechab will never lack a male descendant to serve me.’”
