God calls out to Abraham to stop the sacrifice. (Gen. 22: 11)
Abraham walks away, confused, defeated in carrying out God’s command.
Abraham reaches out to the ghost of Isaac, whose soul fled when he was about to be slaughtered. (Pirkei di Rabbi Eliezer: 31)
Isaac sits next to the altar that he was to die on, contemplating his future.
A figure looks at the sky and contemplates God’s promise to Abraham that his descendants will be as numerous as the stars of the sky if they obey Him or as trod upon as the sand of the sea if they rebel. It could be Abraham or Sarah who has died.
