3. Rabbi Yosi opened the discussion with the verse: "Oh how great is Your goodness, which You have laid up for those who fear You, which You have performed for those who trust in You in the sight of the sons of men!" (Tehilim 31:20). "Oh how great is Your goodness" MEANS how much should people observe and know the ways of the Holy One, blessed be He, for every day a voice resounds and proclaims, saying, 'Beware you people, close the doors of sins, stay away from the net that captures PEOPLE, before your legs are caught in the net.' There is a wheel constantly turning in the world, THE SUPERNAL JUDGMENT. It goes up and down, LIFTS UP AND BRINGS DOWN PEOPLE. Woe to those whose legs are pushed from the wheel, for they fall into a pit kept for the wicked people of the world.
