Литургия к Кохелет 4:12

The Rabbis taught: The Jewish people are beloved, as the Holy One, Blessed be He, surrounded them with mitzvoth: They have phylacteries on their heads, and phylacteries on their arms, and ritual fringes on their garments, and a mezuzah for their doorways. Concerning them David said: “Seven times a day I praise You, because of Your righteous ordinances” (Psalms 119:164). This alludes to the two phylacteries, the four ritual fringes, and the mezuzah, which total seven. And when David entered the bathhouse and saw himself standing naked, he said: Woe to me that that I stand naked without any mitzvah. But once he remembered the mitzva of circumcision that was in his flesh his mind was put at ease, as he realized he was still accompanied by this mitzvah. After he left the bathhouse, he recited a song about the mitzvah of circumcision, as it is stated in the verse: “For the leader, on the Sheminith: A Psalm of David” (Psalms 12:1). This is interpreted as a psalm about circumcision, which was given to be performed on the eighth [ba-Shemini] day of the baby’s life. Rabbi Eliezer ben Ya’akov says: Anyone who has phylacteries on his head, phylacteries on his arm, ritual fringes on his garment, and a mezuzah on his doorway is strengthened from all sides so that he will not sin, as it is stated in the verse: “And a threefold cord is not quickly broken” (Ecclesiastes 4:12). This is interpreted as an allusion to the three mitzvoth of phylacteries, ritual fringes, and mezuzah. And the verse states: “The angel of the Lord encamps round about them that fear Him, and delivers them” (Psalms 34:8).
