Corresponding to the seven heavens, God created seven earths, each separated from the next by five layers. Over the lowest earth, the seventh, called Erez, lie in succession the abyss, the Tohu, the Bohu, a sea, and waters.[23] Then the sixth[24] earth is reached, the Adamah, the scene of the magnificence of God. In the same way the Adamah is separated from the fifth earth, the Arka, which contains Gehenna, and Sha'are Mawet, and Sha'are Zalmawet, and Beer Shahat, and Tit ha-Yawen, and Abaddon, and Sheol,[25] and there the souls of the wicked are guarded by the Angels of Destruction. In the same way Arka is followed by Harabah, the dry, the place of brooks and streams in spite of its name, as the next, called Yabbashah, the mainland, contains the rivers and the springs. Tebel, the second earth, is the first mainland inhabited by living creatures, three hundred and sixty-five species,[26] all essentially different from those of our own earth. Some have human heads set on the body of a lion, or a serpent, or an ox; others have human bodies topped by the head of one of these animals. Besides, Tebel is inhabited by human beings with two heads and four hands and feet, in fact with all their organs doubled excepting only the trunk.[27] It happens sometimes that the parts of these double persons quarrel with each other, especially while eating and drinking, when each claims the best and largest portions for himself. This species of mankind is distinguished for great piety, another difference between it and the inhabitants of our earth. Our own earth is called Heled, and, like the others, it is separated from the Tebel by an abyss, the Tohu, the Bohu, a sea, and waters. Thus one earth rises above the other, from the first to the seventh, and over the seventh earth the heavens are vaulted, from the first to the seventh, the last of them attached to the arm of God. The seven heavens form a unity, the seven kinds of earth form a unity, and the heavens and the earth together also form a unity.[28] When God made our present heavens and our present earth, "the new heavens and the new earth"[29] were also brought forth, yea, and the hundred and ninety-six thousand worlds which God created unto His Own glory.[30] It takes five hundred years to walk from the earth to the heavens, and from one end of a heaven to the other, and also from one heaven to the next,[31] and it takes the same length of time to travel from the east to the west, or from the south to the north.[32] Of all this vast world only one-third is inhabited, the other two-thirds being equally divided between water and waste desert land.
