The second day of creation was an untoward day in more than the one respect that it introduced a breach where before there had been nothing but unity; for it was the day that saw also the creation of hell. Therefore God could not say of this day as of the others, that He "saw that it was good." A division may be necessary, but it cannot be called good, and hell surely does not deserve the attribute of good. Hell has seven divisions, one beneath the other. They are called Sheol, Abaddon, Beer Shahat, Tit ha-Yawen, Sha'are Mawet, Sha'are Zalmawet: and Gehenna. It requires three hundred years to traverse the height, or the width, or the depth of each division, and it would take six thousand three hundred years to go over a tract of land equal in extent to the seven divisions.
