The Torah gives us several names of G-d, which we understand to be different facets (as we understand them) of the divine.
So, for example, Elokim is introduced at the beginning of creation, and it refers to G-d as the Creator of the entire physical world. This facet is powerful but ultimately impersonal, like nature itself.
To the world at large, G-d is the Master of Nature: with the Egyptians, for example, G-d seeks to make them understand that He is more powerful than any and all of the Egyptian pantheon.
The second common name, YKVK, is introduced with the second story of creation, the creation of the world and man as spiritual beings, not just physical animals. This is the facet of G-d with which we seek connection, our soul attracted back to its source. The acronym corresponds to the phrase “I will be what I will be,” containing promise for the future.
Then you shall say to Pharaoh, ‘Thus says YKVK: Israel is My first-born son.
Israel is the first-born son of YKVK, the deity of spiritual connection. Given the “show me” nature of paganism, it is no surprise that Egypt were not impressed by such a fuzzy and non-corporeal concept as a G-d that connects to the human soul. The point may be too subtle for Pharaoh, but it should be clear to us: Egypt was the nation of demonstrable physical forces, the nation with all the pagan deities representing all the forces of nature.
This is because, to the Jewish people, G-d is meant to ultimately be our partner, not just more powerful than other deities, but qualitatively different from all the natural forces, unique and on an entirely different plane. G-d is not meant to be, as with pagan deities, “the god of the sun” or “the god of fertility” even though Elokim means the G-d of all Power, the deity who commands all of nature.
Instead, G-d relates to us through YKVK. The G-d of the Jewish people seeks to have a spiritual connection with His people, seeking to spark our souls and inspire us toward elevation upward. It is not that we leave the physical behind, but that we recognize that what really matters is infusing a spiritual quality into the entire world, just as we do for ourselves (comprised as we are of both a physical body and a spiritual soul). The more aware and conscious we are of the soul, that spiritual spark on loan from G-d, the more it can grow and connect with its source.
Indeed, G-d disapproves of men acting through their physical power. The “Sons of Elokim” are men who identify with natural force, and they act with a “Might Makes Right” attitude, taking whatever women they want. It is noteworthy that this is a conceit that echoes those of mythological pagan deities (who seduce or rape any they desire), but is itself actually uncommon in nature: fewer than 5% of male animals can choose their mate without first gaining the approval of the female of the species.
But the Sons of Elokim, also called “Men of Name” in the Torah, acted like Greek deities – taking with impunity, simply because they could. Their justification was not dissimilar from that of grooming gangs in the UK today, or Andrew Tate’and his Apex Predator mindset. So G-d’s response to that behavior was to weaken men: “My spirit shall not abide in humankind forever, since it too is flesh; let the days allowed them be one hundred and twenty years.”
