In Genesis 1:9-10, we have the account of God's separation of the land and the water, which resulted in the creation of the continents and the oceans. We know that God here summarizes what He did because in Job 38:4-18 God provides us with more of the details of His design for the ocean. As we read the details of Job 38:4-18, we see that God's design anticipates needs which we could never have known about, had the design of the oceans been left up to us.
