12. Rabbi Yehuda began: "Preserve my soul; for I am pious: Save Your servant..." (Tehilim 86:2). One has to look at the end of the verse, and then at the whole verse. At the end of the verse it says, "who trusts in You." HE ASKS, Should it not have said, "who trusts You?" HE ANSWERS: apparently David promised not to be asleep when midnight passed, as it is written: "At midnight I will rise to give thanks to You" (Tehilim 119:62). He should have said, "I arose," but THE MEANING IS, I will arise and be bound to You forever.
13. HE ASKS WHY IT say, "Preserve (Heb. shomrah) my soul," when he should have used the form 'shemor,' since we have learned that there is no letter in the Torah that does not have heavenly and precious secrets. HE ANSWERS 'shomrah,' for he was saying to the Holy One, blessed be He, 'shomrah,' NAMELY SHEMOR (PRESERVE) THE HEI, for it is that same part onto which the soul holds. When the soul leaves this world it enters to inherit the domain of the World to Come. If it so merits, a number of heavenly hosts come out to greet it, guard it, and bring it into its residence in its place. That letter Hei, NAMELY MALCHUT, preserves it, so as to unite with it on new moons and Shabbatot.
14. But if it does not so merit, a number of angels of destruction are directed against it, and push it outside. Woe to that soul that wanders in vain as a stone in the hollow of the sling. This is what was said: "and the souls of your enemies, them shall he sling out, as out of the hollow of a sling" (I Shmuel 25:29). And David made his request before the Holy One, blessed be He, and said, "Preserve my soul" that it be not rejected, and when they come out against it, may the portals be opened for it, and may You accept it before You. "for I am pious...:" HE ASKS, was David really called 'pious?' WAS HE NOT A KING, AND WAS NOT KINGSHIP (MALCHUT) HIS CHARACTERISTIC? Rabbi Yehuda said, Yes, HE WAS CALLED 'PIOUS,' for it is written, "the sure loving promises (Heb. chassadim) of David" (Yeshayah 55:3). THAT IS, SINCE HE WAS RECEIVING CHASSADIM THAT ARE SURE, HE IS 'PIOUS' (HEB. CHASID) and this is the reason for "Preserve my soul," namely, do not abandon it to wander on the outside.
15. Rabbi Yitzchak said: Everyone who has a portion in the Righteous, NAMELY WHO GUARDS HIS COVENANT, inherits this land, THAT IS MALCHUT, as it is said: "Your people also shall be all righteous: they shall inherit the land forever" (Yeshayah 60:21). And this Righteous, WHICH IS YESOD, is called 'pious' SINCE HE BESTOWS CHASSADIM. THAT IS WHY David said, Since I am linked and holding onto that place, UNTO THE RIGHTEOUS, THEREFORE, "I am pious;" and because of this, "Preserve my soul" that it be bound up with You.
