And when Achab was dead, he broke the league which he had made with the king of Israel.

and it cometh to pass at the death of Ahab, that the king of Moab transgresseth against the king of Israel.

But when Ahab was dead, the king of Moab got free from the authority of the king of Israel.

And when Ahab had died, he transgressed the pact that he had with the king of Israel.

But it came to pass, when Ahab was dead, that the king of Moab rebelled against the king of Israel. Who then was Ahaziah; but either through the pusillanimity of his temper, or the sickness that attended him, or the shortness of his reign, he took no steps to the reduction of him, or to oblige him to pay his tribute, which he neglected to do, and is meant by his rebellion.

king of Moab rebelled--This is a repetition of 2-Kings 1:1, in order to introduce an account of the confederate expedition for crushing this revolt, which had been allowed to continue unchecked during the short reign of Ahaziah.
