In early Genesis, God has an important task: To create the world. He could have done so with a breath, a wink, a smile, a thought or nothing at all. Instead, he creates the world in a way that will simultaneously introduce one of the most important ideas in the Torah.
God creates the world with nine, "And God saids" – teaching us how important words are. If God creates his world with words and we are created in his image – then we, too, create our world with words.
This theme continues in the plague sequence in Exodus.
