II Kings 9:25 Jehu said to Bidkar his aide, “Take him up and throw him on the plot of ground belonging to Naboth the Jezreelite. For remember, when you and I rode side by side behind Ahab his father, how the Lord made this pronouncement against him: 26 ‘As surely as I saw yesterday the blood of Naboth and the blood of his sons—declares the Lord—I will repay you on this plot of ground.’ Now therefore take him up and throw him on the plot of ground, in accordance with the word of the Lord.” 27 When Ahaziah the king of Judah saw this, he fled in the direction of Beth-haggan. And Jehu pursued him and said, “Shoot him also.” And they shot him in the chariot at the ascent of Gur, which is by Ibleam. And he fled to Megiddo and died there. 28 His servants carried him in a chariot to Jerusalem, and buried him in his tomb with his fathers in the city of David.
We saw yesterday the infectious effect the house of Ahab had not only on Israel, but Judah as well. When this happened, God had Elisha anoint Jehu as king over Israel. He then used Jehu to take out the kings of both nations - Jotham of Israel and Ahaziah of Judah, on the same day. By clinging together in their evil, they made it easy for him to do so. What evil company is bringing you down?
