Not many scholars have commented verses 6 and 8, might be because they are not easy to be fully comprehended. Maybe we don’t have all the information we need in the Bible.
This expanse or firmament as I understand it is the universe and it also includes the earth, and above it there is water. But the water “under” the firmament that God is talking about must be on earth, and the water above the firmament could be above the universe or outside the universe, (see Genesis 7:11)
In verse 9, God gives His will to the waters below the heaven or the waters on the earth. God’s will is making laws that the creation has to stick to. In this case, He gives His will (law) to the waters to be gathered in one place so the dry land could appear. God is making the shores to limit where the waters could go.
But there will be a time when these laws which God willed into being will be shaken when for instance the waters would pass its limits, we can see this in Matthew 24:29
Matthew 24:29, AMP “Immediately after the tribulation of those days the sun will be darkened, and the moon will not provide its light, and the stars will fall from the sky, and the powers of the heavens will be shaken.”
ASV short note on Matthew 24:29
Jesus is talking about a time in the future when the physical creation will dissolve and the laws of God will be shaken, this is a result of the sin causing the curse. Jesus way of saying it is: “The powers of the heavens will be shaken.”
Back to Genesis 1:9-13. We are now into the third day of the creation and God is talking the vegetation into being, He is dividing it in two, the plants yielding seed and the trees bearing fruit also yielding seed, all according to its kind.
God made the vegetation produce seed to replant itself according to their kind. In fruit you will find seed; on plants, you will find seed. God said according to their kind twice for us to understand that this is vital for the plants and trees.
Today “smart people” are trying to improve God’s creation, to “improve” the plants and the trees. I have been living a while and I remember how the oranges tasted, they were sweet, today they taste like lemons. The same with strawberries they used to be sweet too. Also, plants and flowers were different, nowadays they have more colors, they look beautiful, but they don’t continue to grow like they used to, and they don’t last as long as they used to.
It is easy to misunderstand what I am marking here; we should, of Course, look after our plants and trees, but shouldn’t mess with God’s creation.
- What is the expanse, the firmament?
- Do the waters listen to the words of God?
- What are the shores?
- Can the laws of God be changed?
- What does according to its kind mean?
