2. Come and behold! All Yisrael have a portion in the World to Come. Why is this so? Because they observe the covenant on which the world is established. This is as it is written in the verse: "If My covenant be not day and night, it were as if I had not appointed the ordinance of heaven and earth" (Yirmeyah 33:25), MEANING THAT YISRAEL KEEP IN HOLINESS THE COVENANT OF CIRCUMCISION BY NEVER DESECRATING IT WITH SPILLING OF SEMEN IN VAIN, OR BY SEXUAL IMMORAL BEHAVIOR. Therefore, Yisrael, who has accepted the covenant and observe it, have a portion in the World to Come.
