Contradiction with 2 Samuel 7:12-13
These verses say God will establish the throne of David's offspring forever, while 2 Chronicles 9:31 implies a succession with Rehoboam without mentioning the eternal aspect.
2 Samuel 7:12-13: And when thy days be fulfilled, and thou shalt sleep with thy fathers, I will set up thy seed after thee, which shall proceed out of thy bowels, and I will establish his kingdom.
Contradiction with 1 Kings 2:10-12
1 Kings states that David's son Solomon sat on the throne, already succeeding David, showing continuity, while 2 Chronicles 9:31 shifts focus to Rehoboam succeeding Solomon.
1 Kings 2:10-12: So David slept with his fathers, and was buried in the city of David.
Contradiction with 1 Kings 11:11-13
God tells Solomon the kingdom will be torn away from his son, suggesting a disrupted succession for Rehoboam, which 2 Chronicles 9:31 does not mention as a contradiction to a peaceful succession.
1 Kings 11:11-13: Wherefore the LORD said unto Solomon, Forasmuch as this is done of thee, and thou hast not kept my covenant and my statutes, which I have commanded thee, I will surely rend the kingdom from thee, and will give it to thy servant. [is done...: Heb. is with thee]
Contradiction with 1 Kings 14:21
This verse details Rehoboam being king of Judah after Solomon, similar to 2 Chronicles 9:31, but highlights a divided kingdom, while 2 Chronicles 9:31 does not make this division explicit during Rehoboam's succession.
1 Kings 14:21: And Rehoboam the son of Solomon reigned in Judah. Rehoboam [was] forty and one years old when he began to reign, and he reigned seventeen years in Jerusalem, the city which the LORD did choose out of all the tribes of Israel, to put his name there. And his mother's name [was] Naamah an Ammonitess.
