There's a Definite Pattern

When fullness of thousands of years is reached – major event/person will be 17 years old. Twenty-three actual or inclusive years after that point will bring additional major occurrence to pass.

From Flood 4990 BC to 1990 BC = 3,000 years (Jacob & Esau are 17 years old)

23 years after 1990 BC – in 1967 BC, Jacob/Esau are age 40 and Esau fails the test (Genesis 26:34). 3,023 years from the flood.

From flood 4990 BC to 990 BC = 4,000 years (David is in 17th year of reign)

23 years later in 967 BC, David dies in 40th year of his reign and the temple foundation is laid.

4,023 years from the flood.

From flood 4990 BC to 11 AD = 5,000 yrs. (Jesus is 17 years old)

23 inclusive years later in 33 AD, Jesus dies on the cross/resurrects in 40th calendar year from His birth

5,023 calendar years from the flood.

From flood 4990 BC to 2011 AD = 7,000 years (about 17-year latter rain period ends/judgment begins)

23 inclusive years later in 2033 AD (according to Biblical evidence, Judgment Day concludes and the world ends)

Restating the Biblical Pattern

After fullness of thousands of years is reached from flood date (4990 BC) at time person/event is 17 years, then will follow a 23-year (actual/or inclusive) time period to fulfill or fill up 40 years. The 40th year brings the climax.

4990 to 1990 BC + 23 years = 1967 BC / Esau is 40 – fails test

4990 to 990 BC + 23 years = 967 BC / David dies / 40 year reign ends/foundation laid

4990 to 11 AD + 23 inclusive years = 33 AD / 40th calendar year since birth / Christ dies/resurrects

4990 to 2011 AD + 23 inclusive years = 2033 / 40th inclusive year since 1994 / Biblical evidence points to end of world
