24 And Joram slept with his fathers, and was buried with his fathers in the city of David; and Ahaziah his son reigned in his stead.
25 In the twelfth year of Joram the son of Ahab king of Israel did Ahaziah the son of Jehoram king of Judah begin to reign. 26 Two and twenty years old was Ahaziah when he began to reign; and he reigned one year in Jerusalem. And his mother's name was Athaliah the daughter of Omri king of Israel. 27 And he walked in the way of the house of Ahab, and did that which was evil in the sight of Jehovah, as did the house of Ahab; for he was the son-in-law of the house of Ahab. 28 And he went with Joram the son of Ahab to war against Hazael king of Syria at Ramoth-gilead: and the Syrians wounded Joram. 29 And king Joram returned to be healed in Jezreel of the wounds which the Syrians had given him at Ramah, when he fought against Hazael king of Syria. And Ahaziah the son of Jehoram king of Judah went down to see Joram the son of Ahab in Jezreel, because he was sick.

Commentary on 2 Kings 8:16-24
(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.
