Rabbi Adin Steinsaltz:
God’s speech is not independent of Him, because nothing can conceivably be separate from Him- “there is no place devoid of Him.”
Because there is nothing separate from Him, divine speech, too, must necessarily be connected to Him.
Differentiation between the “I” and the external is relevant only for a human being and has no meaning when applied to God.
