And he added, “and let him not die,” according to our Sages (Tamid 32a), “What should a man do to live? Let him kill himself.” But [Reuben] will live and will not need to “kill himself,” as it is written, What man can live and not see death? (Psalms 89:49). For if one gives life to himself, then without doubt he kills himself, and vice versa. And our Sages said (Sanhedrin 92a), “Let Reuben live in this world, and let him not die in the World to Come.” And because the World to Come is hidden, therefore the life of the World to Come remains hinted at through the precise wording and let him not die.And adjacent to this is And this for Judah, because he too was blessed with the World to Come, as his bones were rolling around, as Rashi explains. Or because it is said, But if a wicked person turns from his way and lives (Ezekiel 33:11), and Reuben was a penitent, therefore it says, Let Reuben live, etc. And this for Judah. For who caused Reuben to confess? Judah, etc. (Sotah 7b).
