Behold the Lamb of God 

As John was preaching his hard message of penance and laying the axe to the root of the tree, he saw all the lambs being brought to Jerusalem for the Passover sacrifice. Josephus tells us that ten or fifteen years after the death of Christ, 260,000 lambs were offered in the temple in Jerusalem. The religion of Israel was a veritable hemorrhage of blood. As John watched this procession of the Passover, Isaac's question was still in the air, 'Where is the lamb for the sacrifice? Where is the lamb?' Suddenly John stopped and looked out at someone in the crowd, interrupted his discourse, and said, 'Look, look, the Lamb of God, who takes away the sin of the world.'
