Again the voice spake: "Put off thy shoes from off thy feet, for the place whereon thou standest is holy ground." These words conveyed the desire of God that he cut asunder every bond uniting him with earthly concerns, he was even to give up his conjugal life. Hereupon the angel Michael spoke to God: "O Lord of the world, can it be Thy purpose to destroy mankind? Blessing can prevail only if male and female are united, and yet Thou biddest Moses separate from his wife." God answered, saying, "Moses has begot children, he has done his duty toward the world. I desire him to unite himself now with the Shekinah, that she may descend upon earth for his sake."
