Abraham's wife Sarah is the only female in Genesis for whom an age is ever mentioned. We can read the span of her life (127 years per Genesis 23:1). However, even in advance of when she became pregnant, Abraham notes she'd "give birth at 90" (Genesis 17:17).
Why might Sarah have had her age recorded in these passages thereby making her the only woman for whom an age is ever mentioned?
Sarah's lifespan was part of an elaborate numerology hidden in the story of the patriarchs. True, her age when she gave birth (90) might have inspired awe among the earliest audience of this story, as would that of Abraham (100) but these numbers were probably chosen mainly because they were easy for tradents to remember as they passed the stories down orally to the next generation.
Sarah's lifespan of 127 years fits into the formula for the three patriarchs, but at a secondary level:
...
Furthering the above formulas, Sarah lived to 127 years, which is the sum of these consecutive square numbers plus 17 (127 = 5 squared + 6 squared + 7 squared + 17). The early Hebrews found the number 17 to have mythic significance. Of all the people in the Book of Genesis, they saw the patriarchs as most important, and Sarah was the supreme matriarch.
I consider this more of an observation than an answer. (If there’s somewhere else I should place this, please let me know).
There are nine numerical signs in Genesis, each having to do with parenthood, each linking parallel Genesis stories with Gospel stories. Jesus’ numbers (i.e. 30, 33, or 3) had to be included in each equation). The totals for these are mostly 333’s, but the final two are 9,999 and 3,333. Sarah’s numbers are required for 4 of the signs, because she had so many parallels with Jesus’ mother Mary.
The signs obviously prove nothing. E.G. Sign #2: Enoch was the only person in Genesis assumed into heaven, 300 years after the birth of his son, Methuselah. Jesus was assumed/ascended into heaven 33 years after the birth of a son (Him). The two together total 333.
Signs #3 through #9 would only be obtained under the following beliefs: • Fatherhood starts at conception • Motherhood starts at conception • Childhood / “life” starts at conception
Sign #3: Sons Sacrificed: Abraham’s “whole span of life” was 175 years. Sarah’s “span of life” was 127 years. They therefore lived to the ages of 174 and 126, respectively. Add 33 years for Jesus from birth to death and the total is 333.
Sign #8: All Genesis Parental Years: This sign requires every number in Genesis (*) in order to calculate all parenthood years for Jesus’ forefathers in Genesis and reaches 9,874. However, when the parallels for Joseph and Mary (i.e. Jacob’s son Joseph who saved his family by getting them to Egypt, and Sarah have their paternal and maternal years added), with 3 for Jesus, the total becomes 9,999.
For Sign #9: All Parental Years After the Flood: All Genesis years prior to the flood must be removed, with Noah having only some paternal years after the flood. Including Joseph’s, Sarah’s, and Jesus’ years the total is 3,333.
Again, these were only numerical signs that proved nothing. However, halfway through finding these I was able to solve the “Two Years After the Flood” enigma, by applying the 3 beliefs noted above, and then look for two more enigmas. All three had the same solution. Genesis supports Pro-Life, mathematically.[https://hermeneutics.stackexchange.com/q/8365/2873]3 https://www.johnmmartin.com/?page_id=936
(*)-The 6 “exceptions”, miscellaneous numbers never used in the 9,999 or any other numerical sign were the following: • Abram’s age when Ishmael was born: 86 • Ishmael’s age at circumcision: 13 • “Span of Ishmael’s life”: 137 • Esau’s age at marriage: 40 • Jacob’s age at marriage: 40 • Joseph’s age when sold to Egyptians: 17
They happened to total: 333
