...more deeply flawed than thinking YHWH is merely a tribal deity? Because it seems to me that would be the inevitable conclusion of the line of interpretation you're suggesting.
I would suggest, kindly, that these esoteric hunts for hidden meanings distract from the gospel. I wasted years on that path. Jesus said the entire OT was about him. He told the Pharisees, in effect, if they read the Scriptures and don't see him, they read them wrongly.
I'm not suggesting you don't see him. Just that these hunts can distract. Just some unsolicited thoughts from a stranger on the interwebs. ✌️
