Contradiction with 2 Samuel 24:16
This verse states that the angel of the Lord was by the threshing place of Araunah the Jebusite during the plague, which differs from the context of the angel sheathing his sword in 1 Chronicles 21:27.
2 Samuel 24:16: And when the angel stretched out his hand upon Jerusalem to destroy it, the LORD repented him of the evil, and said to the angel that destroyed the people, It is enough: stay now thine hand. And the angel of the LORD was by the threshingplace of Araunah the Jebusite. [Araunah: also called, Ornan]
