Rabbi Tovia Singer provides us with the textual context behind the story of the sacrificial lamb.
Once the biblical context behind of the story is understood, it becomes apparent how absurd it is to suggest that the story has anything to do with Jesus. Even within christianity, it is a matter of wide dispute whether or not Jesus is considered the sacrificial lamb by the new testament. Either the last supper was a passover seder, or Jesus was the sacrificial lamb – according to the new testament, only one can be true.
