Genesis 7

71 Noah and his enter into the Ark. 
20 The flood destroyeth all the rest upon the earth.(Well the world of the writer/protagonist anyway)

1 And the ancestors had taught Noah, Enter thou and all thine house into the Ark: for thee have I seen [a]righteous before me in this [b]age. (Have followed the steps of what you have learned from your ancestors)

2 Of every [c]clean beast thou shalt take to thee by sevens, the male and his female: but of unclean beasts by couples, the male and his female.(Clean: cattle, seven equaling the days of the week, coincidence?)

3 Of the fowls also of the heaven by sevens, male and female, to keep seed alive upon the whole earth.
(what does this say? The man of 2400 years ago, knew that you needed male and female of many ‘visible’ animals/mamals. Why cattle by 7 and none-cattle by 2? Because you wouldn’t eat the non-cattle. They knew that if you wanted to survive a flooding of your land;seemingly a very heavy one in the delta, covering everything; you needed to save more then your own hide)

4 For seven days hence I will cause it rain upon the earth forty days, and forty nights, and all the substance that I have made, will I destroy from off the earth. (in a week, it will rain for 40 days and everything your ancestors created will be submerged, gone.)

(Possibly an early like almanac, or datebased schedule told a monsoon season was coming of 1 1/4, to 1 1/2 month.)

5 Noah therefore did according to all that ancestor’s knowledge commanded him.

6 And Noah was six hundred years old, when the flood of waters was upon the earth.
(Is this age accounting to anything? Is this a counter from what event this action was taken? 600 days, years, etc back? Was this on several generations of Noah’s offspring, as they didn’t have lastnames?)

7  So Noah entered and his sons, and his wife, and his sons’ wives with him into the Ark, because of the waters of the flood.

8 Of the clean beasts, and of the unclean beasts, and of the fowls, and of all that creepeth upon the earth,

(we know this would mean the cattle, as clean you could eat AND domestics like dogs or other ‘service’ animals as unclean)

9 There [d]came two and two unto Noah into the Ark, male and female, as the ancestors had commanded Noah.

10 And so after seven days, the waters of the flood were upon the earth.

11  In the six hundredth year of Noah’s life, in the [e]second month, the seventeenth day of the month, in the same day were all the [f]fountains of the great deep broken up, and the windows of heaven were opened,

12 And the rain was upon the earth forty days and forty nights. (are we sure about ‘forty’, not ‘forth’?)

13 In the selfsame day entered Noah with Shem, and Ham and Japheth, the sons of Noah, and Noah’s wife, and the three wives of his sons with them into the Ark
(We have a very strange chronological flow here: We have preparations, then a dating of Noah, then back to the rules, back to preparations, then to the event, then back to the moment of departure)

14 They and every beast after his kind, and all cattle after their kind, and everything that creepeth and moveth upon the earth after his kind, and every fowl after his kind, even every bird of every feather.

15 For they came to Noah into the Ark, two and two, [g]of all flesh wherein is the breath of life.

16 And they entering in, came male and female of all flesh, as the ancestors had told him how to do it: and the historical events (forcasted events) [h][i]shut him in.

17 Then the flood was forty days upon the earth, and the waters were increased, and bare up the Ark, which was lifted up above the earth.

18 The waters also waxed strong, and were increased exceedingly upon the earth, and the Ark went upon the waters.

19 The waters [j]prevailed so exceedingly upon the earth, that all the high mountains, that are under the whole heaven, were covered.

20 Fifteen cubits upward did the waters prevail, when the mountains were covered.

21 Then all flesh perished that moved upon the earth, both fowl and cattle and beast, and everything that creepeth and moveth upon the earth, and every man.

22 Everything in whose nostrils the spirit of life did breathe, whatsoever they were in the dry land, they died.

(Now, here is something that becomes quite obvious: The man of 3400 years ago, that wrote the text, had not often seen fish in its habitat, or had never looked at ‘living fish’. Most likely they hadn’t seen it required yet to investigate how far fish were like other animals. As fish would never die from a flood. Yet, they do breath the ‘spirit of life’)

23 So [k]the flood destroyed everything that was upon the earth (well, all of the land up to the horizon), from man to beast, to the creeping thing, and to the fowl of the heaven: they were even destroyed from the earth. And Noah only [l]remained, and they that were with him in the Ark.

(It is still not a small feat to destroy a whole area, but remember, how would you feel your whole house was destroyed. You would envision it as your ‘life’ being destroyed, you ‘world’ being irradicated.)

24 And the waters prevailed upon the earth an hundred and fifty days.
(This doesn’t mean that they had to stay in the boat for 150 days…I thought it was a year? 150 days plus 40 plus 7, would still not accumulate to 365. The effects of the flood, areas drowned, dangerous with famine, unable to stand in the mud, etc, would linger for some time. Growing food would take some time, likely more to those periods of 150 days. Remember, only in certain seasons you could sow.)
