Hassidout sur Les Psaumes 33:6

This shall be the Torah concerning the one struck with skin blanch [metzora] on the day he becomes clean. He shall be brought to the priest (Lev. 14:2), and our Sages of Blessed Memory interpreted metzora as one who speaks evil [motzi ra], for afflictions come through the sin of evil speech. But the matter is according to what is written, When God began to create etc. (Gen. 1:1), and our Sages of Blessed Memory interpreted: “For the sake of Torah and for the sake of Israel” (cf. Rashi, ad. loc.); so we find that Israel is something very important to Blessed God, since for their sake all of the Worlds and all the Creations were created. And Blessed God takes pleasure from each one of Israel, even from a greatly wicked person: “Your temples [rakatekh] are like a pomegranate (Song of Songs 6:7) – even the empty ones [reykanim] among you are as full of mitzvot as a pomegranate” (Babylonian Talmud, Berakhot 57a). And when a person speaks evil about one of Israel, even if he speaks truth, he nullifies the Blessed Creator’s pleasure (if it were possible) and causes Him sadness (if it were possible) as is stated, [And the Lord …] was saddened in to His heart (Gen. 6:6), and inverts the pleasure [oneg] into affliction [nega]; therefore his “wage” is measure for measure, affliction comes upon him. And our Sages of Blessed Memory said: “Evil speech is as great as idolatry, sexual immorality, and murder” (Babylonian Talmud, Arakhin 15b). But we must be precise: what connection does idolatry have to evil speech? But the matter is according to what is written, By the word of ADONAI were the heavens made (Psalm 33:6), that all of the Worlds and all of the Creations were created through speech comprised of the 22 letters of the Torah, which is called Heavenly Sovereignty. For when the Sovereign does not speak, no one knows how to do His Will; and when he speaks His Will is revealed, and that is Heavenly Sovereignty whose Sovereignty is in all jurisdictions. And we find in Sefer Yetzirah that [the letters] are established in the mouth, that Blessed God established the 22 letters: the World of Speech, Heavenly Sovereignty, the Attribute of ADONAI-ness, ADONAI, open my lips (Psalm 51:17), were established in the human mouth.

Deuteronomy 26,17. “this day you have guaranteed that ‎the Lord will forever be your G’d;” as a general rule the ‎largesse dispensed by G’d for mankind is known as ‎דבור‎, as we ‎know from psalms 33,6: ‎בדבר ה' שמים נעשו וברוח פיו כל צבאם‎, “by ‎the word of G’d the heavens were made and by the breath of His ‎mouth all their host.” Whenever the Jewish people are on a ‎spiritually lofty plateau, it is as if they cause G’d to dispense His ‎largesse for them, whereas if, G’d forbid, they have fallen from ‎that level the Talmud (Gittin 56) likens them to Exodus ‎‎15,11 ‎מי כמך באלם ה'‏‎, which according to the Talmud should be ‎read as ‎מי כמך באלמים‎, “who is like You amongst the “dumb, i.e. ‎silent ones, O Lord?”
‎[The Talmud arrives at this interpretation because the ‎word ‎אלים‎ is written defectively, without the letter ‎י‎ which would ‎indicate the plural mode, Ed.]
This is the allusion in ‎our verse where the Torah speaks –in a complimentary fashion- ‎of Israel as causing G’d to “speak,” i.e. dispense His largesse. ‎Moses adds the word ‎היום‎, “this day,” to indicate that as far as ‎Israel’s status is concerned, each day is viewed as a separate unit, ‎so that they can be credited with their spiritual accomplishments ‎anew each day.‎

"By the word of the LORD were the heavens made; and all the host by the breath of His mouth." (Psalms 33:6), and there is wisdom in all speech, since speech come from the five parts of the mouth (two sets of teeth, two lips and the tongue), and through them were all things and words of creation formed, as it says "You created all in wisdom" (Psalms 104:24).
