Komentaryong Sumisipi para sa Mga Awit 79:13

והנה שם שלשה עדרי צאן, “and here there were three flocks of sheep, etc.” The Torah could have written והנה שלשה עדרי צאן ושם היה באר, “here there were three flocks of sheep and there was a well, etc.” The reason the syntax was changed was to allude to a similar sequence in Ezekiel 3,23: והנה שם כבוד ה' עומד, “and here the glory of G’d was standing.” Israel is called צאנו של מקום, “the flock of G’d,” as we know from Ezekiel 34,31 ואתן צאני צאן מרעתי אדם אתם, “and you are My sheep, sheep of My pasture- you are Adam, etc.” We have another verse expressing the same thought in Psalms 79,13 ואנחנו עמך וצאן מרעיתך, “and we are Your people and the flock of Your pasture.” The reason the Torah mentioned three flocks is that the Jewish people consist of three flocks, i.e. the Priests, the Levites, and the Israelites. All of the Israelites used to make a pilgrimage to the Temple three times a year in order to be in the Presence of G’d.

do for Your name’s sake Do what You will do with us for the sake of the great name that has spread about You that You rule over all and that we are Your people and the flock of Your pasture, and it is not fitting that You give Your victorious name to the idols. And the Midrash Aggadah explains: for the sake of Your name that is inherent in our name.
