I have said, Ye are gods; i.e. "in my Law I have called you gods"—I have given you this lofty name (see Exodus 21:6; Exodus 22:8, Exodus 22:9), since ye judge on my behalf, "as my representatives" (Deuteronomy 1:17; 2 Chronicles 19:6; Romans 13:1, Romans 13:2).
And all of you are children of the Most High. Not therefore "gods" in the strictest sense, but possessing a derived, and so a qualified, divinity.
