Where did the LORD say, "I will repay you in this plot of ground"?

Jehu tells Bidkar to remember how, when "you and I rode together after Ahab his father" (9:25), "the LORD laid this burden on him" (9:25), and gives the words: "Surely I have seen yesterday the blood of Naboth, and the blood of his sons" and "I will repay you in this plot of ground" (9:26). These words are not in 1 Kings 21, which doesn't mention Naboth's sons. There the LORD's word to Ahab by Elijah spoke of the place, "In the place where dogs licked the blood of Naboth, dogs will lick your blood, even yours" (1 Kings 21:19), and of his house, "I will make your house like the house of Jeroboam the son of Nebat" (1 Kings 21:22); and when Ahab humbled himself the LORD said, "I will bring the evil on his house in his son’s day" (1 Kings 21:29). This chapter doesn't say which of these words 9:26 gives in other words, or whether it is more of what was said that day; it gives what Jehu remembered, and says Joram was cast on the plot "according to the LORD’s word" (9:26). Whether the word about the dogs and Ahab's blood was kept at Ahab's death (1 Kings 22:38) or here, in his son's day, is an honest question in 1 Kings 21, which sets out the two main readings without choosing. Both readings agree that 1 Kings 22:38 and 9:26 each say the LORD's word was done.
