"For you will bless the righteous." In the way of the world, when a person gives a liter of gold to his fellow, robbers come and steal it from him, and he loses his gift. But the Holy One, blessed be He, is not like this, rather, "For you will bless the righteous." And not only that, but He also makes a shield for him, as it is said, "The Lord crowns him with favor." It is taught there (Shabbat 63a), "A person shall not go out with a sword or a bow."
"To the conductor on the eighth. This is what is stated (Psalms 119:164): Seven times a day I praise You. Rabbi Yehoshua ben Levi said these are the seven commandments mentioned in the recitation of Shema. [They are]: creation, love, [recitation of] Shema, speaking truth, [affirmation of God as] Redeemer, and [the commandments] concerning tzitzit and adding on to the sukkah of peace. Rabbi Avin in the name of Rabbi Nechemia said [these are] the seven commandments that a person does every day: [recitation of] Shema twice a day, praying three times a day, eating and blessing [before and after], and Rabbi Meir used to say: "Beloved is circumcision, for the Holy One, blessed be He, swore to Abraham that anyone who is circumcised will not descend to Gehenna, as it is said (Genesis 17:14), 'But the uncircumcised male whose foreskin has not been circumcised, that person shall be cut off from his people; he has broken My covenant.' And who goes down there? What is written after that? (Genesis 15:19-21) 'The Kenite, the Kenizzite, and the Kadmonite.'" And so Ezekiel says (Ezekiel 32:19), "Go down and lie with the uncircumcised," and Isaiah says (Isaiah 5:14), "Therefore, Sheol has enlarged its appetite and opened its mouth beyond measure." This is for those who do not have the covenant of circumcision. And where is the term "chok" (statute) mentioned? As it says (Psalms 105:10), "He established it for Jacob as a statute." But for the heretics and sinners of Israel who deny God, they are afflicted with uncircumcision and fall into Gehenna, as it says (Isaiah 9:20), "He has stretched out His hand against them and smitten them." This is because all the commandments that we have are not meant to be scrutinized meticulously, except for the commandment of circumcision and the empty words of the mouths of schoolchildren that have no sin, as it says (Jeremiah 33:25), "If not for My covenant, I would not have appointed the statutes of heaven and earth." For when a person enters the synagogue, he wraps himself in tzitzit and puts on tefillin on his head and arm, and four tzitzit surround him and guard his four corners. And when he enters the bathhouse, he looks at himself and says, "I am now naked of mitzvot (commandments)." And when he looks at the circumcision, which is equivalent to all the commandments, his mind is calmed. When David saw this, he composed a psalm on it, saying, "For the leader, on the eighth [day], a psalm, a song for the dedication of the Temple, of David.
