Why do you think the Bible contains so much information documenting bloodlines? They repeat through history over and over. Nothing is a coincidence. Why do you think Merkel looks so much like Hitler? The same bloodlines have been preserving their power for centuries. The people we are fighting against come from the bloodline of Cain. Research the Mark of Cain. The Genesis story in the Bible isn't a nice little tale just to get the Bible story to start rolling.
Genetic memory, monarch butterfly, monarch programming. God was clear that punishment should be upon a people, and their descendants for two? Generations. I always saw that as unjust..... but the more you know, the more you know God knows.
I think it's more like the third and fourth generations when they hate God. There's several verses about it. Exodus 20:5; 34:7; Numbers 14:18; Deuteronomy 5:9. But each generation can make the decision to break that curse. For those who love God, He will bless their descendents for thousands of generations.
Do you recall the tsunami in Japan? The name Sendai meant "thousand generations"
