Although God had now granted all of his wishes, still Moses received the following answer to his prayer, "I beseech Thee, show me Thy glory": "Thou mayest not behold My glory, or else thou wouldst perish, but in consideration of My vow to grant thee all thy wishes, and in view of the fact that thou are in possession of the secret of My name, I will meet thee so far as to satisfy thy desire in part. Lift the opening of the cave, and I will bid all the angels that serve Me pass in review before thee; but as soon as thou hearest the Name, which I have revealed to thee, know then that I am there, and bear thyself bravely and without fear.'
