This is the book of the generations of Adam. On the day when God created man, He made him in the likeness of God.
Genesis 5:1 (NASB)
Genesis 5 starts out mentioning “the book of the generations of Adam.”
It’s the first time we see this word “book.”
It means “book” or “writing,” but it also means “missive” or “instructions.” Like a decree… or a Promise.
