You did not cite the verse and scripture on that phrase but I will say this. You are looking at this from this centuries views and culture and therefore out of context. "Enjoy as plunder" means it is a gift from God and take it without guilt. God gave them a victory and it was not solely by their own hands they were victorious. The glory belongs to God. Again, I say you are projecting current Western mindset on circumstances which I doubt you can neither imagine nor understand. Have a good day yourself.
It’s all relative, then?
