2 Kings 10:31

Jehu took no heed.. heart] Jehu was a worshipper of the Lord (Jehovah), and, in his violent extirpation of the house of Ahab, was doubtless actuated by religious zeal as well as by motives of ambition, whilst his desire to suppress the worship of Baal which had been encouraged by Ahab and Jezebel was reinforced by indignation at the tyranny manifested by the reigning house in the matter of Naboth: cp. 2 Kings 9:25; 2 Kings 9:26. But the combined revolution and reformation which he effected were accompanied by massacres which, at a later date, excited the abhorrence of the prophet Hosea (Hosea 1:4); and though the religion of Jehovah was restored by him to its previous supremacy, it retained the idolatrous character which Jeroboam I had given it by representing the Deity under the figure of a young bull.
