They mean everything, they are mathematical proof of divine inspiration.
1 + 1 will always = 2
40 different authors over 4000 years could have not collaborated to make the Bible uniquely written as it is, and still produce these numbers. It's impossible.
Those verses can be interpreted and understood easily without needing the book of Enoch.
So you can believe God created the World in 7 days, creating Adam & Eve, the animals, the seas, the air, the heavens and the earth. He created you, our bodies, and everyone & everything in existence. He knows the future, present, and past all at once. He knows everything we are going to do before we do. He is all powerful, all loving, and 100% perfect, pure, and good.
But He can't preserve His Word in pure form for future generations, in their tongue?
Did God not know the English language would be one of the most prominent languages in the World?
Did God mistakenly inspire King James to gather the wisest scholars in the land, 47 men, to translate the Bible, and authorize it with his Royal Decree. Just to produce a Bible with errors or missing books?
Make no mistake, if God can cause Trump to be born 700 years before Israel, and be exactly 70 years, 7 months, & 7 days old on his first day of presidency.
Which would mean before the world was created, He knew exactly how to make that happen, Trumps entire lineage all the way back to Adam & Eve, every ancestor of his, the paths they took, their marriages, their offspring, their movement, their actions.
But somehow, even though God could do all these things, He wasn't able to preserve His Word into English?
Brethren, do not underestimate the power of God. His thinking and ways are infinitely higher than ours.
Isaiah 55:8 - For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD.
Isaiah 55:9 - For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts
That's my whole point. It would be impossible for men to do it on their own, but they didn't.
God states in his Word:
2 Timothy 3:16 - All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
ALL SCRIPTURE IS GIVEN BY INSPIRATION OF GOD << Hence why these mathematical impossibilities exist in the Bible. Every verse & chapter written like there is nothing out of the ordinary, a normal story, a normal book; yet these numbers still exist. It proves only God could have done this.
Matthew 19:26 But Jesus beheld them, and said unto them, With men this is impossible; but with God all things are possible.
