What does 2 Kings 9:27 mean?

When Ahaziah, king of Judah, saw what happened, he ran away toward Beth-haggan. Jehu chased him, shouting, Get him too! They shot Ahaziah in his chariot on the way up to Gur, near Ibleam. He managed to escape to Megiddo, but he died there. 2 Kings 9:27 - Modern Text Bible
