24 And Joram went to rest with his fathers and was put into the earth with his fathers in the town of David: and Ahaziah his son became king in his place.
25 In the twelfth year that Joram, the son of Ahab, was king of Israel, Ahaziah, the son of Jehoram, king of Judah, became king; 26 Ahaziah was twenty-two years old when he became king, and he was ruling in Jerusalem for one year. His mother's name was Athaliah, the daughter of Omri, king of Israel. 27 He went in the ways of the family of Ahab, and did evil in the eyes of the Lord as the family of Ahab did, for he was a son-in-law of the family of Ahab. 28 He went with Joram, the son of Ahab, to make war on Hazael, king of Aram, at Ramoth-gilead: and Joram was wounded by the Aramaeans. 29 So King Joram went back to Jezreel to get well from the wounds which the bowmen had given him at Ramah, when he was fighting against Hazael, king of Aram. And Ahaziah, the son of Jehoram, king of Judah, went down to see Joram, the son of Ahab, in Jezreel, because he was ill.

(Read 2 Kings 8:16-24)
A general idea is given of Jehoram's badness. His father, no doubt, had him taught the true knowledge of the Lord, but did ill to marry him to the daughter of Ahab; no good could come of union with an idolatrous family.
Commentary on 2 Kings 8:25-29
(Read 2 Kings 8:25-29)
Names do not make natures, but it was bad for Jehoshaphat's family to borrow names from Ahab's. Ahaziah's relation to Ahab's family was the occasion of his wickedness and of his fall. When men choose wives for themselves, let them remember they are choosing mothers for their children. Providence so ordered it, that Ahaziah might be cut off with the house of Ahab, when the measure of their iniquity was full. Those who partake with sinners in their sin, must expect to partake with them in their plagues. May all the changes, troubles, and wickedness of the world, make us more earnest to obtain an interest in the salvation of Christ.
