Hi TD, its nice to be able to chat freely. I'm not a great one for staying on topic. It can feel very restictive.
Yes the Bible is clear. Ziv is the 2nd months and there is no other kind of cross ref for it. The Bible sticks to this. It's only when so-called scholars wade in and try to moved things around by suggesting the months have a different order that uncertainty enters. Actually its not uncertainty it utter confusion. Such ones paved the way for Watchtower.
The Bible is easy to understand, it starts off really gently showing how time is counted with Adam up to Lamech. Gets tiny bit more complex with Noah and so it continues as if supporting you to improve your skill and keeping track of time. Minimal detail is use and the numbering cannot be viewed independent of the actual events/lives of men. Therefore comprehension of the history goes with monitioring the passage of time.
For example - regarding the 2nd month, Watchtower encourages us to view it as October (!!!!!). The Bible actually says the 2nd month is Ziv, spring time (April/May). Just imagaine you are getting a lot of animals off a boat, down a mountain and letting them loose, what would be the best time to do it? October (not a lot to eat) or a beautiful spring with lots of yummy green shoots pushing forth?
*** w03 5/15 pp. 4-5 Noah’s Log—Does It Have Meaning for Us? ***
Noah divided the year into 12 months of 30 days each. In ancient times, the first month started about the middle of our calendar month of September. The floodwaters began to fall in “the second month, on the seventeenth day of the month” and continued falling for 40 days and 40 nights during the months of November and December 2370 B.C.E.
(Genesis 7:11) . . .In the six hundredth year of Noah’s life, in the second month. . .
(1 Kings 6:1) . . .And it came about in the four hundred and eightieth year after the sons of Israel came out from the land of Egypt, in the fourth year, in the month of Ziv, that is, the second month, after Sol′o‧mon became king over Israel, that he proceeded to build the house to Jehovah. . .
