Contradiction with 2 Samuel 8:13
This verse attributes the defeat of the Edomites in the Valley of Salt to David, not Jehoram as in 2 Kings 8:21.
2 Samuel 8:13: And David gat [him] a name when he returned from smiting of the Syrians in the valley of salt, [being] eighteen thousand [men]. [smiting: Heb. his smiting]
Contradiction with 1 Chronicles 18:12
It states that Abishai, not Jehoram, defeated 18,000 Edomites in the Valley of Salt, differing from 2 Kings 8:21's account.
1 Chronicles 18:12: Moreover Abishai the son of Zeruiah slew of the Edomites in the valley of salt eighteen thousand. [Abishai: Heb. Abshai]
Paradox #1
2 Kings 8:21 describes a battle involving King Jehoram of Judah. A contradiction or inconsistency arises when comparing this with 2 Chronicles 21:9, where the same event is described. The accounts differ slightly in details about the battle and its outcomes. Such discrepancies can create confusion about the precise historical events.
