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."
