One God Spoke All the Words and the Refusal of Two Powers

"And God spoke all these words" (Exodus 20:1). Rabbi Isaac said: From the beginning of the world's creation, "The beginning of Your word is truth" (Psalms 119:160). No creature can claim that two powers gave the Torah or that two powers created the world. It is not written here "In the beginning they created," but rather "In the beginning He created" (Genesis 1:1). It is not written here "And they spoke," but rather "And God spoke." "And God spoke all these words" (Exodus 20:1): what the mouth cannot speak and the ear cannot hear. And it says, "God has spoken once; twice have I heard this" (Psalms 62:12). And it says, "Is not My word like fire?" (Jeremiah 23:29). And it says, "Come out, you three, to the Tent of Meeting" (Numbers 12:4), teaching that the three of them were called in a single utterance.
