Not enough that the palace was guarded by a host, at each entrance two lions were stationed, and in terror of being torn to pieces none dared approach the doors, and none could go within until the lion tamer came and led the beasts away. Now Balaam and all the other sacred scribes of Egypt advised that the keepers loose the lions at the approach of Moses and Aaron. But their advice availed naught. Moses had but to raise his rod, and the lions bounded toward him joyously, and followed at his feet, gambolling like dogs before their master on his return home.
