Truly I can not divulge a competent understanding to you, as mine is only an exploratory understanding and interest.
Sorry to mislead you, as I was simply suggesting that the quicker we get away from thinking about "jealous" as we think in modern times and dismiss the text (which I am not suggesting you did that) but clearly others use that word by itself to mock and make fun of...
When we look at a phrase like, "God not bearing any rival" it might simply suggest "bearing" means creating or birthing, and if that is the case, and God created everything, it seems to be a declaration that God created everything but never did God create anything his equal.
This explanation goes well with much of the Old Testament, where God warns over and over, don't treat anything like it is God.
Could be a simple a candid statement by God, that while somethings are glorious and reflect God's great ability to create, don't mistake the
creation for the creator.
This is no way implies a childish immature jealousy we might usually equate with the word jealous, IMO.
So that is my unscholarly two cents, and I look forward to getting slammed by Jay!
and learning more.
