Likutei Moharan 57:9/ליקוטי מוהר"ן נ״ז:ט׳

19. This is the explanation of: They asked Rabbi Yosi son of Kisma: “When will the son of David come?” and he answered them: “When this gate will fall [and be rebuilt, fall and be rebuilt, and fall. Then, before they have enough time to rebuild it, the son of David will come].”

2The main point is that it will fall three times, and they will not have enough time to rebuild it before the son of David comes. For the gate of Aram is the aspect of the gate of the Other Side. When it falls one fall after another by means of the aspects I have brought, as mentioned above, then the son of David will come and build the gate of holiness.

3That is, when there is no faith in the sages and no one listens to them—in the aspect of “laying a snare for the rebuker at the gate” (Isaiah 29:21)—because of this they take ill, until they have no cure, in the aspect of “they reached the gates of death” (Psalms 107:18). But when they have faith, then the gates of holiness open up for them, in the aspect of “Open the gates… he that keeps faith” (Isaiah 26:2). And when one rises, the other falls. Thus the gate of Aram falls one time.

4Faith is built up by means of a vow, and then it shines with the lights of the patriarchs, as mentioned above. Then the gate of holiness is built a second time, in the aspect of “Lift up your heads, O gates” (Psalms 24:7). For the patriarchs are the heads, in the aspect of “These are the heads of the patriarchal houses” (Exodus 6:14). And when one rises, the other falls. This is the aspect of the gate of Aram falling a second time.

5And through the lights of the patriarchs one merits ShaBbaT, “lehaShBiT [the] enemy,” and he merits peace, as mentioned above. Then the gate of holiness is built a third time, in the aspect of “render peace-promoting justice in your gates” (Zekhariah 8:16), and in the aspect of charity—”Do not oppress the pauper in the gate” (Proverbs 22:22). Thus, they subdue the enemies who draw sustenance from the gate of Aram, in the aspect of “Those who sit by the ShaAR (gate) talk about me” (Psalms 69:13), because “the liver [that] is angry”—which is Esav-Edom, as mentioned above, for he is “like a mantle of Sei’AR (hair)” (Genesis 25:25)—has been subdued. This is the gate of Aram falling a third time.
