Talmud sobre Provérbios 12:26

There are seven realms: the upper realm, the lower realm, the air of the world, and the four upper areas. Rabbi Meir says: There are seven skies: Vilon, Rakia, Shekhakim, Zevul, Ma’on, Machon, and Aravot. The land, likewise, is called by seven names: Eretz, Adama, Arka, Haravah, Yabasha, Tevel, and Heled. And why is it called Tevel? Because it is seasoned (metubelet) with everything. Another interpretation: Because its nature is to bring in and not to take out.³It outlasts all, because it consumes but does not withdraw.
There are seven distinctions between one righteous person and another: One has a more pleasant wife than the other; one has more pleasant children than the other; both eat from one bowl, but this one tastes according to what he has done and that one tastes according to what he has done; both of them dye cloth with the same kettle, but this one’s comes out lovely and that one’s comes out ugly; one’s wisdom is greater; one’s understanding is greater; and one’s knowledge is greater (and one is taller), as it says (Proverbs 12:26), “The greater one guides the righteous.”
