Musar su Isaia 33:6

Thus, this "fear" is really "love" and it is of this that Isaiah says: "And the fear of the Lord is his treasure" (Is. 33:6).

It is written in the Torah, "And now, Israel, what doth the Lord thy God require of thee, but to fear the Lord thy God?" (Deut. 10:12). And it is writen, "You must revere the Lord your God" (ibid., 10:20). And it is written, "And the fear of the Lord which is His treasure" (Is. 33:6). And they said (Shabbath 31b, and see Berakoth 33b), "The Holy One has nought in His world save for the awe of Heaven," as it is written, "And unto man he said, "Behold (hen), the fear of the Lord, that is wisdom" (Job 28:28). (The fear of the Lord is unique in God's affections — Rashi, (ad. loc.) The Hebrew word hen can be interpreted to mean "one" for in Greek they pronounce the word "one" as "hen."

Nothing in the world outweighs reverence — not silver, not gold, not pearls and not all the hidden treasures; they are all as nothing when compared to reverence for the Holy One, Blessed be He. For it is said, "Fear of the Lord which is His treasure" (Is. 33:6). Therefore, a man should hasten to treasure up in his heart a thing that is the very treasure of the Holy One, Blessed be He, and a man should learn in this world that every man tries to hoard all the good that he can. And one who can store up the things that kings treasure will certainly do so. If this is the case, then where is there a man who will not treasure up that which is treasured by the King of Kings, the Holy One, Blessed be He?
