18 And he walked in the way of the kings of Israel, as the house of Ahab had done, for the daughter of Ahab was his wife. And he did what was evil in the sight of the Lord. 19 Yet the Lord was not willing to destroy Judah, for the sake of David his servant, since he promised to give a lamp to him and to his sons forever. 20 In his days Edom revolted from the rule of Judah and set up a king of their own. 21 Then Joram[1] passed over to Zair with all his chariots and rose by night, and he and his chariot commanders struck the Edomites who had surrounded him, but his army fled home. 22 So Edom revolted from the rule of Judah to this day. Then Libnah revolted at the same time. 23 Now the rest of the acts of Joram, and all that he did, are they not written in the Book of the Chronicles of the Kings of Judah? 24 So Joram slept with his fathers and was buried with his fathers in the city of David, and Ahaziah his son reigned in his place.
25 In the twelfth year of Joram the son of Ahab, king of Israel, Ahaziah the son of Jehoram, king of Judah, began to reign. 26 Ahaziah was twenty-two years old when he began to reign, and he reigned one year in Jerusalem. His mother's name was Athaliah; she was a granddaughter of Omri king of Israel.

(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.
