Contradiction with 1 Samuel 8:11-12

1 Samuel 8:11-12: And he said, This will be the manner of the king that shall reign over you: He will take your sons, and appoint [them] for himself, for his chariots, and [to be] his horsemen; and [some] shall run before his chariots.
Contradiction with 1 Samuel 13:19-22
Contrasts with 1 Chronicles 27:1 by describing a time when the Israelites were disorganized and lacked weapons, unlike the organized divisions in 1 Chronicles 27:1.
1 Samuel 13:19-22: Now there was no smith found throughout all the land of Israel: for the Philistines said, Lest the Hebrews make [them] swords or spears:
Contradiction with 2 Samuel 24:9
Contradicts by providing a different account of the number of Israelite men able to bear arms compared to the divisions mentioned in 1 Chronicles 27:1.
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 21:1-5
Contradicts by showing the negative consequences and divine disapproval of a census, whereas 1 Chronicles 27:1 is part of an organized military structure.
1 Chronicles 21:1-5: And Satan stood up against Israel, and provoked David to number Israel.
Paradox #1
The possible contradiction or inconsistency might be with the organization and structure of the military divisions described, as they may not align with other historical records or accounts found elsewhere in the Bible, which sometimes depict different systems or numbers regarding Israel's military.
