according to Genesis 7:11, on Cheshvan 17 Noah entered the ark, and the Lord shut the door behind him.
i believe Cheshvan is the month called 'Bul' in the Bible
found in this verse:
"And in the eleventh year, in the month Bul, which is the eighth month, was the house finished throughout all the parts thereof, and according to all the fashion of it. So was he seven years in building it."
word by word breakdown found here:
note total gematria of verse = 4500
base conversions show a prominent place for that number -
2368 dec = 4500 oct = 940 hxd
2368 greek geamtria for Jesus Christ.
940 (9:40) my theoretical pick for the exact time of the Resurrection due to this base conversion association, and for other reasons.
it also might be noted that Bul is sited as the 8th month in the text, and the gematria total of 4500 is in base 8 (Octal). Noah was one of Eight that was saved. The Lord was raised on the 8th day, thus eight is a resurrection number, which is well known.
