Musar su Salmi 3:78

And likewise the group of destroyers of the vineyard of the Lord - such as those that cause the masses to sin - are haters of the Lord. As you would say that people that destroy the cities of the king or his vineyards and orchards are haters of the king. And it is stated (Isaiah 5:7), “For the vineyard of the Lord of Hosts Is the House of Israel, and the seedlings he lovingly tended are the men of Judah.” And it is stated (Psalms 83:4), “They plot craftily against Your people, take counsel against Your treasured ones.” And it is stated (Psalms 83:6), “Unanimous in their counsel they have made an alliance against You.” And it is stated (Psalms 2:2), “and regents intrigue together against the Lord and against His anointed.” Therefore our Rabbis, may their memory be blessed, said (Rosh Hashanah 17a) that those that sinned and cause the masses to sin descend to Gehinnom, and are judged there for generations and generations.

One who has time should also recite the following verses, each of which alludes to a different limb: “And as for You, Hashem, You shield me, my soul, and lift up my head (Tehillim 3:4). “I proclaim righteousness among a large congregation, behold I will not refrain my lips; You know this, Hashem” (Tehillim 40:10). I called to Him with my mouth and exaltation was beneath my tongue” (ibid., 66:17). “Hashem’s instructions are upright, causing the heart to rejoice; Hashem’s commandments are pure, illuminating the eyes” (ibid., 19:9). “Hear the sound of my supplication when I cry out to You, when I lift up my hands towards Your holy sanctuary” (ibid., 28:2). “To do Your will, my God, was my desire, and Your Torah was within my intestines” (ibid., 40:9). “All my bones will declare, Hashem, “Who is like You?’ ” (ibid., 35:10). “I will bless Hashem who advised me, even at night my kidneys rebuke me” (ibid., 16:7). My foot stood upon a plain, among congregations I will bless Hashem” (ibid., 26:12). Afterwards let him recite this Mishnah encompassing the entire body from top to bottom: One may only stand to pray in a spirit of weighty- headedness [i.e., solemnity]. The pious of earlier times would pause for an hour before praying in order to direct their hearts towards the Omnipresent One. Even if the king asks after his welfare and even if a snake is wrapped around his heel he must not interrupt. Afterwards let him say the verse, “The end of the matter when everything is heard is to fear God and keep His commandments, for that is the entirety of a man” (Koheles 12:13). This verse alludes to the observance of all 613 commandments. Whoever conducts himself in this manner will enjoy good fortune, selah.

When David says in verse 9: ואל ה' אתחנן, this means that he pleaded on behalf of G–d, or the שכינה, Divine Presence, which is forced into exile alongside the Jewish people. When the time for salvation arrives, the שיכנה also experiences salvation, i.e. לה' הישועה על עמך (Psalms 3,9) and Israel experiences חנינה, compassion and favor. Berachot 7a, expresses this idea graphically when we are told that Rabbi Yishmael ben Elisha (a High Priest) once entered the Holy of Holies in order to offer the incense offering. While inside, he had a vision of Akatriel (one of the names of G–d) sitting on a throne asking him: "Yishmael My son, bless Me!" The High Priest responded by saying: "May it be Your will to suppress Your anger etc…. and to treat Your children with the attribute of Mercy."
