O my LORD, I am not eloquent, neither heretofore, nor since thou hast spoken unto thy servant: but I am slow of speech, and of a slow tongue.

In the last heaven Moses saw two angels, each five hundred parasangs in height, forged out of chains of black fire and red fire, the angels Af, "Anger," and Hemah, "Wrath," whom God created at the beginning of the world, to execute His will. Moses was disquieted when he looked upon them, but Metatron embraced him, and said, "Moses, Moses, thou favorite of God, fear not, and be not terrified," and Moses became calm. There was another angel in the seventh heaven, different in appearance from all the others, and of frightful mien. His height was so great, it would have taken five hundred years to cover a distance equal to it, and from the crown of his head to the soles of his feet he was studded with glaring eyes. "This one," said Metatron, addressing Moses, "is Samael, who takes the soul away from man." "Whither goes he now?" asked Moses, and Metatron replied, "To fetch the soul of Job the pious." Thereupon Moses prayed to God in these words, "O may it be Thy will, my God and the God of my fathers, not to let me fall into the hands of this angel."

And Moses said: Our Lord, surely Thou hast given Pharaoh and his chiefs finery and riches in this world's life, our Lord, that they may lead (people) astray from Thy way. Our Lord, destroy their riches and harden their hearts, so that they believe not till they see the painful chastisement.
