The third story is found in Genesis 1.3-5. “And God said, ‘Let there be light’, and there was light and God saw that the light was good and he separated the light from the darkness and God called the light ‘day’, and the darkness he called ‘night’ and there was evening, and there was morning, the first day”.

Hebrew, like English, has a word for one and a different word for first. The same is true for the words two and second, three and third, etc. As an example the Hebrew word for “three” is “shelosh”, and the Hebrew word for “third” is “sheliyshiy”. Days 2 - 7 use the Hebrew word for second, third, fourth, etc. We would assume that the “first” day would use the Hebrew word “reshon” meaning “first” in order to be consistent with the other six days, but instead we have the word “echad” meaning “one” or ” in unity”. The author is making a parallel with the “first” day and with all the days of creation. I believe this is because all seven days of the fattening of the earth are being united in this verse. The first day of creation is also a parallel with the whole of creation as the earth was in darkness and the act of filling the earth brought light to the earth.

The first story is found in Genesis 1.1 “In the beginning God created the heavens and the earth.” The Hebrew word “bara” is a verb and is usually translated as “create”. To really understand what this word means let us look at another passage where this word is used.

1 Samuel 2.29 - Why do you scorn my sacrifice and offering that I prescribed for my dwelling? Why do you honor your sons more than me by fattening yourselves on the choice parts of every offering made by my people Israel?’ The word “fattening” in the passage above is the Hebrew word “bara”. The noun form of this verb is “beriya” and can be found in Genesis 41.4 - “And the cows that were ugly and gaunt ate up the seven sleek, fat cows.” The word “fat” is the Hebrew word “beriya”.

The word “bara” does not mean, “create” (Hebrew actually has no word that meaning “create” in the sense of something out of nothing) but “to fatten”. If we take the literal definition of “bara” in Genesis 1.1 we have - In the beginning God fattened the heavens and the earth.

As science is learning that the Big Bang is not something out of nothing, but reality out of the zero energy field or the finite out of the infinite.

Acts 17 24 God that made the world and all things therein, seeing that he is Lord of heaven and earth, dwelleth not in temples made with hands; 25 Neither is worshipped with men’s hands, as though he needed any thing, seeing he giveth to all life, and breath, and all things; 26 And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation;

27 That they should seek the Lord, if haply they might feel after him, and find him, though he be not far from every one of us:

28 For in him we live, and move, and have our being; as certain also of your own poets have said, For we are also his offspring. 29 Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man’s device.
