Genesis 5 Math as Heilsgeschichte

Here is a visual demonstration regarding Methuselah's "age" of 969, that it's not a real age, since it is the sum total of all the first 17 triangle numbers (between 1 and 153). Note that 153 is the number of fish caught by the disciples when they were having difficulty and the resurrected Christ helped them, in John 21. You can see it in the following table and looking at the table explains what a triangle number is as well:

1
3 = 1+2
6 = 1+2+3
10 = 1+2+3+4
15 = 1+2+3+4+5
21 = 1+2+3+4+5+6
28 = 1+2+3+4+5+6+7
36 = 1+2+3+4+5+6+7+8
45 = 1+2+3+4+5+6+7+8+9
55 = 1+2+3+4+5+6+7+8+9+10
66 = 1+2+3+4+5+6+7+8+9+10+11
78 = 1+2+3+4+5+6+7+8+9+10+11+12
91 = 1+2+3+4+5+6+7+8+9+10+11+12+13
105 = 1+2+3+4+5+6+7+8+9+10+11+12+13+14
120 = 1+2+3+4+5+6+7+8+9+10+11+12+13+14+15
136 = 1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16
153 = 1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17

969 (adding up the sum total of all the triangle numbers)

Therefore, 153 is a resurrection number in and of itself, where if you do:

1x1x1 = 1
5x5x5 = 125
3x3x3 = 27

Therefore, 1 + 125 + 27 = 153 again!

So, Methuselah's "age" hints at the coming (resurrected) Messiah. This is all that is really going on here, and these "ages" have hidden numeric (and even in this case) prophetic meanings, and therefore are not literal. For more information, check out: Genesis 5 Math as Heilsgeschichte
