Дварим 4:39 Галаха: Mishneh Torah, Foundations & Mishneh Torah, Shofar, Sukkah and Lulav

This is as the prophet says: "But the Lord God is the true God" (Jer. 10.10); He alone is the Truth, and no other being possesses a truth similar to His Truth, even as the Torah says: "There is none other like unto Him" (Deut. 4.35), meaning, there is no other true being, besides Him, like unto Him.

Behold, it is clearly indicated in the Torah and in the Prophets that the Holy One, blessed is He! is Incorporeal for it is said: "That the Lord, He is God in heaven above and upon the earth beneath" (Deut. 4.39); a corporeal being is incapable of being in two places simultaneously; and it is also said: "For ye saw no manner of form" (Ibid.–15); and it is moreover said: "To whom will ye liken me, that I should be equal?" (Isa. 40,25); had He been corporeal He would be like other bodies.

We may not mention malkhiot, zikhronot and shofarot of punishment — such as [in] zikhronot, "And all flesh shall remember that, etc." (Psalms 78:39); [in] malkhiot, "with outpoured anger shall I rule over you" (Ezekiel 20:33); [and in] shofarot, "Blow the shofar on the mountain, etc." (Hosea 5:8). Nor [may we mention] the remembrance of an individual — even if it was for good — such as "Remember me, O Lord, in the desire of Your people" (Psalms 106:4); and "Remember me, my God, for the good" (Nehemiah 13:31). And recollections (pikdonot) — such as "I have surely recalled you" (Exodus 3:16) — are not the same as remembrances. But one may mention the punishment of idolatrous nations, such as "The Lord reigned, nations tremble" (Psalms 99:1); "Remember the day of Jerusalem to the Children of Edom" (Psalms 137:7); [and] "the Lord, God, will blow with the shofar, and go in the storms of the south" (Zechariah 9:14). All of these verses: "Hear Israel, the Lord, our God, the Lord is one" (Deuteronomy 6:4); "You have been shown to know" (Deuteronomy 4:35); "And you shall know today and place upon your hearts, etc." (Deuteronomy 4:39) — their content is kingship. Even though there is no mention of kingship [in them], it is surely like, "The Lord will reign forever and ever" (Exodus 15:18); [and] "And then He became King in Jeshurun, etc." (Deuteronomy 33:5).
