This angel is sixty myriads of parasangs taller than his fellows, and at every word that passes out of his mouth, issue twelve thousand fiery lightning flashes. When he beheld Moses he roared at him: "What dost thou here, son of Amram, here on the spot of the Holy and High?" When Moses heard his voice, he grew exceedingly frightened, his eyes shed tears, and soon he would have fallen from the cloud.
But instantly the pity of God for Moses was awakened, and He said to Hadarniel: "You angels have been quarrelsome since the day I created you. In the beginning, when I wanted to create Adam, you raised complaint before Me and said, 'What is man that Thou are mindful of him!' and My wrath was kindled against you and I burned scores of you with My little finger. Now again ye commence strife with the faithful one of My house, whom I have bidden to come up here to receive the Torah and carry it down to My chosen children Israel, although you know that if Israel did not receive the Torah, you would no longer be permitted to dwell in heaven."
When Hadarniel heard this, he said quickly to the Lord: "O Lord of the world! It is manifest and clear to Thee, that I was not aware he came hither with Thy permission, but since I now know it, I will be his messenger and go before him as a disciple before his master." Hadarniel hereupon, in a humble attitude, ran before Moses as a disciple before his master, until he reached the fire of Sandalfon, when he spoke to Moses, saying: "Go, turn about, for I may not stay in this spot, or the fire of Sandalfon will scorch me."
