Then God sent the Angel Jephipha, who brought back all to his remembrance; and, armed with the law, Moses passed the ranks of all the angels, and each gave him some secret or mystery; one the art of mixing simples, one that of reading in the stars, another that of compounding antidotes, a fourth the secret of name, or the Kabalistic mystery.[530] It is said by the Mussulmans, that when the law was declared to the children of Israel by Moses, they refused to receive it; then Mount Sinai rose into the air, and moved above them, and they fled from it; but it followed them, and hung over their heads ready to crush them. And Moses said, “Accept the law, or the mountain will fall on you and destroy you.” Then they fell on their faces and placed the right side of the brow and right cheek against the ground and looked up with the left eye at the mountain that hung above them, and said, “We will accept the law.” This is the manner in which the Jews to this day perform their worship, says Tabari; they place the brow and right cheek and eye upon the ground, and turn the left cheek and eye to heaven, and in this position they pray.[531] 7. THE MANNA. (Exod. xvi.) All the time that Israel wandered in the wilderness they were given manna, or angels’ food. This food is ground by the angels in heaven, as Moses saw when he was there. For when Moses was in heaven, he knew not when it was night and when it was day, till he listened to the song of the angels; and when they sang “Holy God,” then he knew it was morning below on earth; and when they sang “Blessed be thou,” he knew it was evening below. Also he observed the angels grinding the manna and casting it down; and then he knew it was night, and they were strewing it for the Israelites to gather in the morning.[532] It is in the third firmament, called Schechakim (clouds), that the mills are in which manna is ground.[533] Along with the manna fell pearls and diamonds, and on the mountains it was heaped so high that it could be seen from afar.[534]
