Hi, sorry to have taken so long. (Christmas)
I have made several adjustments to my original ideas, but the basic premise remains - that there exists in scripture an ancient calendar different from modern soli-lunar calendars. Thanks for pointing out where improvements were needed.
Here is
my updated paper with charts and diagrams included:
And
here is an updated video. I hope you find it as interesting as I have in studying it.
I notice you have revised the period of 17719 days to a period of 17718 days.
Some additional thoughts:
The month names "Ziw" (1 Kings 6.1), "Bul" (1 Kings 6.38) and "Ethanim" (1 Kings 8.2) are Canaanite/Phoenician names. They occur in the account of the building of a Phoenician temple by Phoenician craftsmen because the author is relying on Phoenician sources, or because the author wants to give some additional Phoenician color to his account. That they are not Israelite names is suggested by the way the author has to explain them, for example, "the month of Ziw, which is the second month." The Israelite tradition seems to have been to number the months, not name them. Do not think "Aviv" an exception. חדש האביב means no so much "Month of Aviv" as "
Season of Aviv" or "Season of new grain."
There is no evidence that the jubilee year was ever observed in the preexilic period. The Babylonian Talmud is not a reliable source for the history of 11th-century BC society.
Indeed there is no evidence that the law of the jubilee year was ever "law" as we understand the term. Comparisons to cuneiform documents support the idea that the written laws were not statutes in our sense. They described the law, but they were not the law itself. The nearest modern equivalents are law-journal articles and legal hypotheticals. In the preexilic period the laws of release and jubilee may never have been more than wishful thinking on the part of one school of legal thought. The only preexilic release that is attested in Scripture is described in Jeremiah 34.8ff, and it is not an automatic release previously scheduled, but a release proclaimed by the king.
Nor is it certain that the Israelite year always began in the Spring. The Gezer calendar, a Hebrew inscription of the 10th century BC begins year in the Fall:
Two months of ingathering
two months of seed
two months of late seed
one month of cutting flax
one month of barley harvest
one month of harvesting and measuring
two months of gleaning
one month of summer fruit.
At some point the first month of the year was changed to the Spring for some purposes, perhaps under Babylonian influence. Exodus 23.16 dates the feast of ingathering to "the end of the year", but Exodus 34.22 dates it to "the
turn of the year" according to some interpreters, perhaps reflecting this change.
