Were Jehorams' sons made prisoners or were they killed? 2 Chronicles 21:16-17 and 2 Chronicles 22:1

2 Chronicles 21:16-17 The LORD aroused against Jehoram the hostility of the Philistines and of the Arabs who lived near the Cushites. They attacked Judah, invaded it and carried off all the goods found in the kings palace, together with his sons and wives. Not a son was left to him except Ahaziah, the youngest.

2 Chronicles 22:1 The people of Jerusalem made Ahaziah, Jehoram's youngest son, king in his place, since the raiders, who came with the Arabs into the camp, had killed all the older sons. So Ahaziah son of Jehoram king of Judah began to reign.
