I see what you are saying. The only problem is that God doesn’t condemn in any way what Jacob and Rebekah did to preserve the rightful blessing.
True enough, which is a bit surprising in a way. But he does clearly show the consequences of what they did, the broken relationships and animosity that had to be overcome. In the end Jacob was forgiven (he obviously had to ask forgiveness and it was given) but their relationship was evidently never the same. Esau moved away and stayed away if I remember correctly.
David comes to mind with his endless collection of wives and concubines. I don't remember God directly condemning it but he does rather clearly show the disastrous consequences.
Its funny that Jacob wound up with a father-in-law that had the same mentality he did, and they spent the next couple of decades trying to get the better of one another on this deal or that one. Funny.
This is just me thinking out loud, you understand, continuing the discussion. I'm interested in your view.
