The commander of the army of Hadadezer, king of Zobah. He led the combined Ammonite-Syrian forces in a battle against Israel. King David's army defeated Shobach's forces completely, killing Shobach himself. This decisive victory broke the Ammonite-Syrian alliance. As a result, the kingdoms that had been under Hadadezer's control became subject to David instead (2 Samuel 10:16–18). He is also called Shophach in 1 Chronicles 19:16–18.
