Likutei Moharan 15:7/ליקוטי מוהר"ן ט״ו:ז׳

17. And this is the explanation of [the opening verse]: “You will be to Me a kingdom of prie st s and a holy nation. {These are the devarim (words) that you should daber (speak) to the Children of Israel.}”

2kingdom — This corresponds to the revealed Torah, because with it “kings rule” (Proverbs 8:15). Kingship is the aspect of revealed, for a king without a nation is no king. And everyone has need of a king, because “everyone requires the grain merchant.”

3priests — This is synonymous with prayer, the aspect of Avraham. As our Sages taught: The Holy One said to Avraham (Psalms 110:4), “You are a priest forever” (Nedarim 32b).

4and a holy nation — This is the aspect of the Holy Temple—the hidden Torah which is called holy. And how can we merit achieving these aspects? by elevating and binding the aspect of fear to knowledge through the aspect of judgment, as above. And this is:

5These are the devarim (words) which you should daber (speak) — This corresponds to fear which is called “word.” This is because the essence of speech is there [in fear], as our Sages taught: When a person has fear of Heaven, his words are listened to (Berakhot 6b). Moshe is the aspect of daat. This is, which you should daber — specifically [“daber”]! And this is: “If they should have davar (a word) between them, they come to me” (Exodus 18:16) —because Israel, who is the aspect of judgment, elevates and binds fear to Moshe, to the aspect of daat. And this is:

6to the Children of Israel — Specifically! for they are the aspect of judgment, as in, “His statutes and His judgments to Israel.”

7Thus, by binding fear to the aspect of daat through judgment, we merit revealed Torah. Through the revealed Torah we merit prayer. And through prayer, we merit the mysteries of the Torah.

8DaVaR — This corresponds to fear, as is written (Malakhi 3:16), “Then those who fear God niDBRu (spoke).”
