Rob Skiba also dove into the Nephelim connection with the tribes that the Israelites were ordered to wipe out. Gen 6 "there were giants in those days, and also after", meaning the deluge was an effort to wipe out the nastiness of the pre-flood world with all these fallen creatures and giants running around and killing each other, eating people, fornicating with animals, and aborting their babies. They apparently weren't completely wiped out, because the OT goes on to document other giants, King Bashan I believe and also Goliath. Also when Joshua's group went into the promised land and saw the inhabitants, "we were as grasshoppers to them". Fallen angels corrupted mankind so it made sense to wipe them and their progeny out. Atheists get hung up on this and call God a "genocidal maniac" because of it. Rob Skiba was killed by the COVID protocol a few years ago. Is there a title to your friend's lecture so I can listen to it?
