Genesis 6:3 King James Version (KJV)
3 “And the Lord said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.“
This is an informative passage of scripture. I have often heard folks trying to debunk the Bible because there was “no way Noah lived to be over 900 years old.” But, that statement itself is debunked by Genesis 6:3, when God specifically changed the lifespan of man to 120 years. That’s pretty close to what it is today. God didn’t give much specificity in the creation story, but he made up for that in other places in the Bible in including this verse.
For everything in the Bible man has confused about in one scripture, it is explained in another. For every time we read the word, there are many new ahah moments.
