Genesis 6. There were once giants, God has a tantrum.

Genesis 6

1 And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them,
    So. When the population grew and there were lots of girls and women...

2 That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.
    Men looked at the women and thought, these women are quite nice, I should take one (or two) for a wife. This is quite a reasonable response, there would be no Noah if there were no 'wives'.

3 And the LORD said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.
    I think this line is saying that since man is short lived God will be with man in spirit during his mortal lifetime. I wonder if one-hundred-and-twenty years is a new limitation since the lifespans of the people for the last sixteen-hundred years have been quite a lot longer.

4 There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.
    Really? we haven't met those before. I read this as, 'There were once giants and then, after men and women started to breed the giants were relegated to history and were only seen in stories.' Where did this giants come from. were they pre-existing in the earth, in the waters that god didn't create? are they, like so many other things we have encountered outside of God's scope for creation?

5 And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
    God judged that man was wicked and evil. Probably because he offers protection only to murderers and began the whole thing with a lie about trees.

6 And it repented the LORD that he had made man on the earth, and it grieved him at his heart.
    Did god regret making Adam/man?

7 And the LORD said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them.
    OK. God has decided to kill everything. What did the animals do to deserve this? Presumably after he does this and the fowl of the air are all killed, heaven will only contain a big light, a smaller light and some stars?

8 But Noah found grace in the eyes of the LORD.
    OK.

9 These are the generations of Noah: Noah was a just man and perfect in his generations, and Noah walked with God.
    I'll bet it wasn't as long a walk as Enoch got.

10 And Noah begat three sons, Shem, Ham, and Japheth.
    OK.

11 The earth also was corrupt before God, and the earth was filled with violence.
    What does God expect? He protects *only* murderers!

12 And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth.
    OK. Man is bad for the planet.

13 And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth.
    "I will destroy them with the earth"? an earthquake perhaps?

14 Make thee an ark of gopher wood; rooms shalt thou make in the ark, and shalt pitch it within and without with pitch.
    OK.

15 And this is the fashion which thou shalt make it of: The length of the ark shall be three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits.
    Long and narrow.

16 A window shalt thou make to the ark, and in a cubit shalt thou finish it above; and the door of the ark shalt thou set in the side thereof; with lower, second, and third stories shalt thou make it.
    This is some vessel.

17 And, behold, I, even I, do bring a flood of waters upon the earth, to destroy all flesh, wherein is the breath of life, from under heaven; and every thing that is in the earth shall die.
    God actually intends to kill everything and everyone. There is a population of tens-of-thousands by now and God wants to kill every last one of them, babies, the old, hunters and farmers, mothers and fathers, puppies and kittens, everything! He plans to use water, here he is again manipulating that which he did not create.

18 But with thee will I establish my covenant; and thou shalt come into the ark, thou, and thy sons, and thy wife, and thy sons' wives with thee.
    OK, Nice guy that God. I'll save one family out of thousands.

19 And of every living thing of all flesh, two of every sort shalt thou bring into the ark, to keep them alive with thee; they shall be male and female.
    and a pair of every kind of animal, I'm guessing this makes drowning puppies OK?

20 Of fowls after their kind, and of cattle after their kind, of every creeping thing of the earth after his kind, two of every sort shall come unto thee, to keep them alive.
    OK

21 And take thou unto thee of all food that is eaten, and thou shalt gather it to thee; and it shall be for food for thee, and for them.
    Food is good.

22 Thus did Noah; according to all that God commanded him, so did he.
    
    Noah followed the instruction without question. What gave Noah the impression that God was even capable of making good on this threat? God hasn't demonstrated anything on this scale before and presumably told Noah he was going to do it while walking about with him, I'm not sure I'd have believed God on this one.

Conclusions.

There were giants! before man was created by God! where on or in earth did they come from?
God thinks that genocide is a good cure for debauchery.

I'll comment on the rest after this flood story unfolds.

Next Genesis 7.
