Because I fully understand that the prophets were writing about themselves, and their time---and the concerns that they had in their culture.
And as well I fully accept that what the bible has to say is not all about me, me, me.
You apparently have missed that.
Further, when folks come up with this idea, like you have, they have done so by cherry picking a phrase or two, and then say, "aha, see?????????? the Bybull says right here that.................."
Get an education, honey.
And read the bible for what it is... the folk lore of a group of bronze age goat herders, who, believe it or not, had no clue that you, or the nations that exist today, would ever be here..... that was 2500-3000 years ago.....
And the world still isn't about you, you, you.
