Jehovah is liberal; or, whom Jehovah impels.
(1.) A son of Shimeah, and nephew of David. It was he who gave the fatal wicked advice to Amnon, the heir to the throne (2 Samuel 13:3-6). He was very "subtil," but unprincipled.
(2.) A son of Rechab, the founder of a tribe who bound themselves by a vow to abstain from wine (Jeremiah 35:6-19). There were different settlements of Rechabites (Judges 1:16; 4:11; 1 Chronicles 2:55). (see RECHABITE.) His interview and alliance with Jehu are mentioned in 2 Kings 10:15-23. He went with Jehu in his chariot to Samaria.

je-hon'-a-dab (yehonadhabh, either "Yahweh is noble" or "liberal," or "Yahweh has impelled") = Jonadab (yonadhabh, same meaning):
(1) Jehonadab in the Hebrew of 2 Samuel 13:5; but Jonadab in English Versions of the Bible, and in Hebrew and English Versions of the Bible of 13:3, 12, 35; son of Shimeah, King David's brother. He was friendly with Amnon his cousin, and is said to be "a very shrewd (the Revised Version (British and American) "subtle") man." He planned to get Tamar to wait upon Amnon. Two years after, when Absalom had murdered Amnon, and David had heard that all the king's sons were assassinated, Jehonadab assured him that only Amnon was killed; and his reassuring tone is justified (2 Samuel 13:35); possibly he knew of Absalom's intentions. Septuagint, Lucian, has "Jonathan" in 2 Samuel 13:3;; and in 2 Samuel 21:21 parallel 1 Chronicles 20:7, there is mentioned a son of Shimei (= "Shimca," 1 Chronicles 2:7 = "Shammah," 1 Samuel 16:9), whose name is Jonathan.
See JONATHAN, (4).
(2) Jehonadab in 2 Kings 10:15, 23; in Hebrew of Jeremiah 35:8, 14, 16, 18 = Jonadab in Jeremiah 35:6, 10, 19, and English Versions of the Bible of 35:8, 14, 16, 18, "son" of Rechab, of the Kenite clan (1 Chronicles 2:55). Jehonadab is described in 2 Kings 10 as an ally of Jehu in the olition of Baal-worship in Samaria. Jehu met him after slaying the son of Ahab (10:15); the second part of the verse should probably be translated "And he greeted him and said to him, Is thy heart upright (with me) as my heart is with thee? And Jehonadab answered, Yes. Then spake Jehu (so the Septuagint), If so, give me thy hand. In Jeremiah 35 (where English Versions of the Bible has Jonadab throughout), he is called the "father" of the Rechabites, who derived from him their ordinances for their nomadic life and abstention from wine.
