2 Kings 3:2-3

He put away the image of Baal It was much that his mother, who had brought this worship with her from the Zidonians, should suffer him to remove this image; but she was probably a little daunted at the many disasters which had befallen their family, and was contented with worshipping Baal in private. Nevertheless, he cleaved unto the sins of Jeroboam Though he put away the image and worship of Baal, resolving to worship Jehovah only, yet he continued to worship him under the representation of a calf, which was idolatry, though in a less degree. This kind of worship all the kings of Israel kept up, as a wall of partition between their subjects and those of Judah. They intended hereby to keep their people from going up to worship at Jerusalem, lest, if they did so, they might, by degrees, be brought to submit again to the kings of Judah. Thus Jehoram: he had a little religion, such as it was, but not enough to overrule his policy.
