Passage 2 Samuel 10:18
After the same battle 2 Samuel 10:18 says David killed the men of 700 chariots and 40,000 horsemen, while 1 Chronicles 19:18 says 7,000 chariots and 40,000 foot soldiers. The numbers and the kind of troops both differ.
And the Syrians fled before Israel, and David killed of the Syrians the men of 700 chariots, and 40,000 horsemen, and wounded Shobach the commander of their army, so that he died there.
