In the second heaven Moses saw the angel Nuriel, standing three hundred parasangs high, with his retinue of fifty myriads of angels, all fashioned out of water and fire, and all keeping their faces turned toward the Shekinah while they sang a song of praise to God. Metatron explained to Moses, that these were the angels set over the clouds, the winds, and the rains, who return speedily, as soon as they have executed the will of their Creator, to their station in the second of the heavens, there to proclaim the praise of God. In the third heaven Moses saw an angel, so tall it would take a human being five hundred years to climb to his height. He had seventy thousand heads, each head having as many mouths, each mouth as many tongues, and each tongue as many sayings, and he together with his suite of seventy thousand myriads of angels made of white fire praised and extolled the Lord. "These," said Metatron to Moses, "are called Erelim, and they are appointed over the grass, the trees, the fruits, and the grain, but as soon as they have done the will of their Creator, they return to the place assigned to them, and praise God." In the fourth heaven Moses saw a Temple, the pillars thereof made of red fire, the staves of green fire, the thresholds of white fire, the boards and clasps of flaming fire, the gates of carbuncles, and the pinnacles of rubies. Angels were entering the Temple and giving praise to God there. In response to a question from Moses Metatron told him that they presided over the earth, the sun, the moon, the stars, and the other celestial bodies. and all of them intone songs before God. In this heaven Moses noticed also the two great planets, Venus and Mars, each as large as the whole earth, and concerning these he asked unto what purpose they had been created. Metatron explained thereupon, that Venus lies upon the sun to cool him off in summer, else he would scorch the earth, and Mars lies upon the moon, to impart warmth to her, lest she freeze the earth. 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.
