According to the author of 2 Chronicles, Solomon did not make the people of Israel his workers or servants. Instead, they were soldiers and leaders in his army to help protect the kingdom.
2 Chronicles 8:9: But of the children of Israel did Solomon make no servants for his work; but they [were] men of war, and chief of his captains, and captains of his chariots and horsemen.
2 Chronicles 8:9 may present a contradiction because it mentions using people for forced labor, which might conflict with the values of kindness, fairness, and freedom that are also present in biblical teachings. This could raise questions about the consistency of these values with the practice of forced labor.
