Arrived in the fifth heaven, Moses saw hosts of angels, whose nether parts were of snow and their upper parts of fire, and yet the snow did not melt nor was the fire extinguished, for God had established perfect harmony between the two elements. These angels, called Ishim, have had nothing to do since the day of their creation but praise and extol the Lord.
In the sixth of the heavens were millions and myriads of angels praising God, they were called 'Irin and kadishim, "Watchers" and "Holy Ones," and their chief was made of hail, and he was so tall, it would take five hundred years to walk a distance equal to his height.
