Contradiction with 2 Samuel 24:9
This verse lists 800,000 valiant men who drew the sword in Israel and 500,000 in Judah, which contrasts with the numbers in 2 Chronicles 13:3, where Judah has 400,000 and Israel 800,000, highlighting a discrepancy in military sizes.
2 Samuel 24:9: And Joab gave up the sum of the number of the people unto the king: and there were in Israel eight hundred thousand valiant men that drew the sword; and the men of Judah [were] five hundred thousand men.
Contradiction with 1 Chronicles 21:5
Similar to 2 Samuel 24:9, this verse also states that Israel had 1,100,000 men and Judah had 470,000, again differing from the account in 2 Chronicles 13:3, showing inconsistency in the enumeration of fighting men.
1 Chronicles 21:5: And Joab gave the sum of the number of the people unto David. And all [they of] Israel were a thousand thousand and an hundred thousand men that drew sword: and Judah [was] four hundred threescore and ten thousand men that drew sword.
