On returning to Hebron, Jacob came to the river Jabbok, a tributary of the Jordan. After he had sent his caravan across, he was left alone and a man, in reality an archangel, wrestled him there till daybreak. Unable to prevail the archangel touched the hollow of Jacob's thigh who then withered. Jacob demanded to be blessed before letting the man leave and he did by saying 'your name shall no longer be Jacob, but Israel, because you strove with God and with men, and prevailed'. The scene represents the Christian spiritual struggle on earth.
