Likutei Moharan 6:9/ליקוטי מוהר"ן ו׳:ט׳

19. In general, this entire matter is encompassed in the shape of the aleph, which consists of an upper point, a lower point, and a vav. Consider this very carefully.

2This is also connected to what the Sages taught: Upon entering the Holy Land, the Jewish people were charged with three mitzvot: to kill off the seed of Amalek; to build a Holy Temple for themselves; and to appoint a king.

3Killing off the seed of Amalek is the aspect of Yehoshua, the lower point. This is because blotting out Amalek is essentially dependent upon Yehoshua, as is written (Exodus 17:9), “[Moshe said to Yehoshua, ‘Pick some men for us, and] go out and battle against Amalek,’” and as <this> is explained in the Zohar (II, 65b).

4Building themselves a Holy Temple is the aspect of Moshe, the upper point. This is because “When someone has knowledge, it is as if the Holy Temple was built in his lifetime.” And Moshe is the aspect of knowledge, <as is known>.

5Appointing a king is the aspect of firmament, the vav in the middle of the aleph. As is written, “A star will go forth from Yaakov,” which indicates that a king will arise out of Yaakov. “A star will go forth” alludes to the firmament, which contains stars and constellations. Thus, “from Yaakov,” because “Yaakov was a man of perfection who remained in the tents”—an aspect of firmament, as in, “and He stretched them out like a tent.” [And] as is explained in the Zohar (III, 244b): Yaakov is the aspect of vav.

6For these three mitzvot are the aspect of repentance. Understand this.
