In the first chapter of the bible’s Book of Genesis, the opening account of creation, the Deity calls the matter of the world out of chaos and into a harmonious order. Seven times, coinciding with the seven days of the creation story, God said that it was “good,” and in the final declaration of the world’s goodness, God, in seeing all that was made, proclaims, “Indeed, it was very good.”
The Hebrew word "tov," is translated into English as “good,” implies functionality. When God says that the creation is tov, the inference is the world will function well. With the final affirmation that, “Indeed, it is very tov,” the deeper meaning is the world, more than working well, will work beautifully.
The seven assertions that the creation is good, along with seven days of the creative process, are symbolic of the wholeness of creation. The number seven is regarded as an expression of such wholeness throughout the world.
