신명기 4:35 해설: Rashi, Ibn Ezra, Sforno & Rabbeinu Bahya

הראת — Understand this as the Targum has it: Thou hast been shown. When the Holy One, blessed be He, gave the Torah, He rent open to them the seven heavens, and just as he rent open the higher regions so did He rend open the lower, so that they saw that He was alone (sole God). On this account it is stated, "Thou hast been shown that thou mayest know [that the Lord is God, there is none besides Him]" (Pesikta Rabbati 20 towards the end).

You have been shown a verb in the passive, hof‘al form. I have already explained the word God [comment on Genesis 1: 1]. This word denotes a mysterious and profound concept. God has shown you all these things, so that you shall know that He alone is God.

אתה הראית, G’d has shown you all this.
