Jehonadab
Jehonadab (; meaning Jehovah is willing; Latin: Jonadab) was the son of Rechab. He is mentioned in the Hebrew Bible at 2 Kings 10:15-31. Though not a Jew himself, he was a supporter of Jehu, son of Nimshi, in the elimination of the house of Ahab and in suppressing worship of Baal throughout Samaria. In the Book of Jeremiah he is called Jonadab.
He prohibited his followers from drinking alcohol, and is credited with founding the Rechabites. He also commanded that they live in tents, rather than houses. At Jeremiah 35:6-19, his followers are commended for adhering to his instructions, and God promises that his lineage will continue.
