I can always count on you to give us the WTBTS 'spin' on things. *rolls eyes*
I've heard of people who 'died' at Canyon Lake north of us. Yuppers... they go into the water, and then find out that they cain't swim... and whaddya know... they just up and die - right there on the spot. I don't think they've had anyone actually 'drown' at that lake.
Black Sheep -
Recheck your figures... the bibles that I used (NOT the one issued by the JWs) indicate that Lamech died about 5 years prior to the flood.
Yall be sure to check out my spreadsheet. I have the numbers all there. Did it on a lark one day.
Of course... it's all made up by the Isrealites whilst they were in captivity - but it's fun to look at.
Now... if you do a little reading - outside the bible (I think that it's in 'The Book of Adam' - or one of those) - you'll find out that ol' Methuz knew of the upcoming flood - and knew that he wasn't gonna survive - and called all his family together, and told everyone good-bye. Another good fairy tale.
It's been a while since I read that collection of fairy tales... but I also believe that it was requested of Noah to take the sarcophogas of Adam from the cave where it had been laying in state (Cave of Treasures?) - and put it on the ark, and take it through the flood. (I think Noah got so excited to depart the ark after the flood, that he forgot it and left it on the ark.)
Anyway... it makes a good bedtime story.
