leviticus - speaking of the 7 x 390 years of punishment
26:18 `And if unto these ye hearken not to Me, -- then I have added to chastise you SEVEN times for your sins;
26:21 `And if ye walk with Me `in' opposition, and are not willing to hearken to Me, then I have added to you a plague SEVEN times, according to your sins,
26:24 then I have walked -- I also -- with you in opposition, and have smitten you, even I, SEVEN times for your sins;
26:28 then I have walked with you in the fury of opposition, and have chastised you, even I, SEVEN times for your sins.
4:5 And I -- I have laid on thee the years of their iniquity, the number of days, three hundred and ninety days; and thou hast borne the iniquity of the house of Israel.
4:6 And thou hast completed these, and hast lain on thy right side, a second time, and hast borne the iniquity of the house of Judah forty days -- A DAY FOR A YEAR -- a day for a year I have appointed to thee.
in 745 BC was the beginning of this chastisement of the house of israel.
the first invasion of israel and captivity started in this year with the tribes of reuben, gad and half of manasseh, by the assryians
by 722 BC the whole house was captive
745BC to 1948 = 2,693 years in our calender
390x7 = 2,730 JEWISH prophetic years of 360 days
2,730x360 = 982,800 days
982,800/365 days = 2,692.6 years (the difference being a matter of months)
exactly as prophesied israels chastisement ended and became a sovereign nation again in 1948
if you want to split hairs and say it should be 365.24 days, the average is actually 365.03 days, if you include the leap years from 1582, and the previous 365 days before that time
