The plural in this case is literal. “Elohim” is the plural of “Eloah”. The first chapter of the gospel of John expands on its literality, as does Hebrews 7.
re: “The plural in this case is literal. Elohim is the plural of Eloah.”
You are correct that “Elohim” is plural, and what’s interesting the article preceding Elohim is for singular, not a plural. This is why some New Testament scholars believe that the “we” passages with the singular article reflect the idea of “many” in one (the Trinity?).
Also, for those who say the “we” is due to the “royal we” that was used in King James time must remember that that is not the reason the “we” is used - it is used because it is in the Hebrew text itself, but there was no royal “we” usage in Old Testament times. That was a later european practice.
