Au chef des chantres, à l’octave. Psaume de David.
Jerusalem Talmud Berakhot
It was stated297Tosephta Menaḥot 6:24–25, a parallel to the entire paragraph in slightly different language. A parallel in the Babli (Menaḥot 43b) has the formulation that “every man in Israel is obliged to recite 100 benedictions every day.” In the Yerushalmi and the Tosephta, not only benedictions are counted but all religious deeds, and it is asserted that the number 100 is reached automatically. in the name of Rebbi Meïr: There is no one in Israel who does not perform 100 commandments every day. He recites the Shema‘ and benedictions before and after, eats his bread and recitesbenedictions before and after, prays 18 benedictions three times and then he performs other commandments and recites benedictions after them. Similarly, Rebbi Meïr used to say: There is no man in Israel who is not surrounded by commandments: Tefillin on his head, tefillin on his arm, a mezuzah on his door, circumcision in his flesh, and the four ẓiẓiot of his tallit surround him. That is what David said (Ps. 119:164): I praised You sevenfold every day for Your just laws298In order to end up with a count of seven, the Yerushalmi (and the Yerushalmi source Midrash Tehillim 12) must consider tefillin as one commandment. In Babli and Tosephta, circumcision is not counted, probably because the fact of circumcision goes to the credit of the parents, not the baby, and, therefore, tefillin must count for two commandments.. And so it says (Ps. 34:8): The angel of the Eternal camps around those that fear Him and rescues them299The implication being that the angel is created by the good deeds of the person protected.. When he300David. entered the bath house, he saw himself naked. He said, woe to me that I am stripped of commandmends. When he looked at his circumcision, he started to acclaim the Holy One, praise to Him (Ps. 12:1): For the director, on the eighth301Taken not as an eight-stringed harp but the commandment performed on the eighth day., a song from David.
Menachot
The rabbis taught, “Beloved is Israel, since the Holy One, blessed be He, surrounded them with commandments: On their heads are tefillin and on their forearms are tefillin, and tsisit (fringes) are on their clothes and a mezuzah on their entrances; and about them it states (Psalms 119:164), 'Seven times a day have I have praised You for Your righteous judgments.' And at the time that David entered the bathhouse and saw himself standing naked, he said, 'Woe is to me that I am standing naked without commandments.' And once he remembered about the circumcision on his flesh, his mind was put at ease. After he left, he said song about it, as is stated (Psalms 12:1),
Menachot
'For the choirmaster upon the Sheminit (an eight stringed instrument, which also means, the eighth), a psalm of David' - about the circumcision that was given on the eighth [day]."
