Mat 1
17 So all the generations from Abraham to David are fourteen generations; and from David until the carrying away into Babylon are fourteen generations; and from the carrying away into Babylon unto Christ are fourteen generations.
Apparently God is a dispensationalist
Genesis is the name given to the first book of Moses when the Septuagint was interpreted because it tells the "toledoth"
https://biblehub.com/hebrew/8435.htm of the heaven and earth and Adam, Noah, Abraham ect.
The concept of the seven days,generations is in many Jewish teachings. Jubilees is 120 sets of 50 so 120x50=6000. The Jews say it's the year 5759 because their counting off six one thousand year days. Adam was told the earth would bring forth thorns and thistles and he would work by the sweat of his brow. Six days thou shalt labor and on the seventh rest,,,,1(work),2(work),3(work)4(work),5(work),6000(work),,,7'th(Millennial rest and no work).
It's somthing that has been believed and taught from the beginning and in our modern days some are figuring out bits and pieces of it and calling it Dispensationism. That's why their list is similar to the list I gave.
