These are the generations of the heavens and of the earth when they were created, in the day that the LORD God made the earth and the heavens,
All Commentaries on Genesis 2:4 Go To Genesis 2
John Chrysostom
AD 407
Notice again, I ask you, the insight of this remarkable author, or rather the teaching of the Holy Spirit. I mean, after narrating to us detail by detail all the items of creation and going through the works of the six days, the creation of human beings and the authority granted them over all visible things, now he sums them all up in the words, "This is the book about the origins of heaven and earth when they were created." It is worth enquiring at this point why it is he calls it the book of heaven and earth in view of the fact that the book contains many other things and teaches us about a greater number of matters about the virtue of good people, about God's loving kindness and the considerateness he demonstrated in regard both (99c) to the firstformed human being and to the whole human race, and about a lot of other things it would be impossible to list right now. Don't be surprised, dearly beloved; after all, it is the custom with Holy Scripture not to describe every thing to us in detail in every case but rather to begin with a summary of related items and to leave further detail to be considered by rightminded listeners as they take in what is said.
So that you may learn this is the case, I will make it clear from the very verses just now read. What I refer to is this: notice Sacred Scripture taught us in detail in the preceding verses the creation of everything, but now, instead of mentioning them all, it says: "This is the book about the origins of heaven and earth when they were created, on the day God made heaven and earth," and so on. Do you see how it con fines the whole account to heaven and earth, leaving us to get from them a sweeping view of all the other things? (99d) I mean, when it said heaven and earth, it included everything together in those words, both things on earth and things in heaven. So, just as in its account of created things it doesn't mention them all one by one but gives a summary of related items and makes no further attempt to describe them to us, so too it called the whole book the book about the origins of heaven and earth, even though it contains many other things, evidently leaving us to work out from the reference to these two that all visible things are of necessity contained in this book, both those in heaven and those on earth.
