Likutei Moharan 102:2/ליקוטי מוהר"ן ק״ב:ב׳

12. This is the meaning of [the opening verse]: {“You shall be in charge of my court, and by your mouth shall all my people be supervised; by the throne alone shall I be greater than you.”} You shall be in charge of my court—“Court” refers to fear, as our Sages, of blessed memory, taught: Woe to the one who does not own a courtyard… (Shabbat 31b). That is to say, as a result of the tzaddik ruling with the fear of God,

2and by your mouth shall all my people be supervised—Onkelos renders this into Aramaic as: “by your [mouth’s] utterance”—namely, prayer; “shall all my people be sustained”—i.e., the flow of bounty will be aroused in the world.

3And this is: by the throne alone—This is the diminution of Malkhut. This is because “alone” signifies a limit, and “throne” refers to Malkhut.

4shall I be greater than you—In other words, the diminished Malkhut, who at present is in a limited state, will be made greater through you. For through the strength of prayer with the fear of God one draws down an influx of bounty into the world, and His Malkhut is thereby made great, as explained above.
