KETURAH is not Hagar: the biological clock

Rabbinic tradition claims Abraham’s ‘new’ wife Keturah (Ge. 25:1) was, in fact, a returning Hagar.   But this idea is an impossibility based on age and fertility.

Rashi to Gen. 25:1 states emphatically -- citing Genesis Rabbah 61 – that Keturah was Hagar.  That Hagar had remained ‘pure’ and never remarried after her expulsion by Sarah (Gen. 21: 9-14) and now reunited with Abraham after Sarah’s death.

This tradition is accepted by Chatam Sofer, Chizkuni, Mizrachi, Daat Zkenim, Gur Aryeh and Kli Yakar.

Chomat Anakh even states she is Hagar based on gematria, the idea that words with the same numerical value are interchangeable.  So he sees the standard term for ‘Hagar the Egyptian’ somehow equivalent to Gen. 25:1’s phrase another woman named Keturah”.  

To do so he plays fast and loose: omits the Hebrew definite article meaning ‘the’ – הָ in ‘Hagar the Egyptian’ (now reduced to 948) and somehow sees the Hebrew קְטוּרָֽה וּשְׁמָ֥הּ אִשָּׁ֖ה as equivalent though it adds up to 306 + 351 + 320 = 977![i]

 

However, Ibn Ezra, Radak and Rashbam reject this Keturah is Hagar mindset[ii].   

The dispute, in fact, is a recurring issue: whether one is to take the Bible at its literal wording: its plain meaning or peshat, or to seek hidden meanings that often contradict the plain wording of Scriptures.  

In this case, is it a new woman named Keturah or is Keturah a euphemism meaning ‘sweet’, so Hagar -- after being expelled for 52 years  -- can return and live happily ever after with Abraham.

I, for one, always rely on the peshat.

There is also a piece of evidence that none of the above seems to have been aware of, the midrash Sefer HaYashar. 

I was unaware of its existence until I stumbled upon it in the online Sefaria Gen. 25:1  right sidebar under midrah.[iii]

The work is generally attributed to the Middle Ages as some place names are of Medieval origin. But the name Sefer HaYashar is referred to twice: in Joshua 10:13 and 2 Samuel 1:18.[iv]

And I believe its section on Gen. 25 re: Keturah and her sons is an authentic, ancient text.

As noted in the Joshua and Samuel references, there was a book of ancient history parallel to the Chumash which contained additional information; similar to the Book of the Wars of God mentioned in Num. 21: 14-15 and as the book of battles referred to in Exodus 17:14.[v]

The section of Sefer HaYashar adds much factual information for these minor and essentially unimportant characters. Namely, the offspring and grandchildren of the youngest  three sons not mentioned in the Bible: children who probably would not have been born until after Abraham’s death (an idea raised by Radak to Gen. 25:3[vi]).  And the cities and areas they settled in.

Aside from all this extensive genealogical information, it twice identifies Keturah as a Canaanite.

 

In previous blogs I have argued  the equation of Hagar with Keturah is unfeasible on various grounds, and here add the factors of age and the biological clock of women.

The Bible never gives the age of Hagar when she was given by Sarah to 85 year old Abraham to produce a child – hopefully, a male heir.

Within a year, when Abraham was age 86, she gave birth to Ishmael (Gen. 16: 15-16).

Now let us assume she was a very young handmaiden, possibly in her early 20s or even a teenager, say age 15, when given to Abraham.

What then would be her age at Sarah’s death?

Abraham was 10 years older than Sarah (Gen. 21:5) and since Sarah died at age 127, Abraham was 137 at this point.

As for Hagar, even if she had been age 20 or even age 15 when she cohabited with 85 year old Abraham some 52 years beforehand, Hagar would now be at least 67 or, more likely, in her 70s.

As will be argued in detail in the next blog, “KETURAH – Abraham’s 3rd round of fatherhood”, Abraham was not likely to remarry immediately on Sarah’s death: out of respect and mourning for his beloved wife, and especially as Isaac continued to lament her absence for 3 years: only snapping out of his morose once his arranged bride, Rebecca, arrived and he installed her in his mother’s tent (Gen. 24:67) and they married.  Isaac now being age 40 (Ge. 25:20). 

Only once the newlyweds move out to their own homestead would Abraham be free to pursue a new life companion and bed-mate.

And by this point, Hagar would certainly have been in her 70’s if not far older.

 

It is here that the biological facts of female reproduction and menopause come into play.

Sarah laughed when she overheard the three visitors telling Abraham she would bear him a son next year -- when she would be 90, as she was “old” and had already passed menopause long before (Gen. 18:11).

Menopause is the inflection point of female fertility: after which any remaining ovary eggs no longer drop into the fallopian tubes[vii] (leading to the uterus) where contact with male sperm causes conception, thereby leading to a fetus and child. [viii]

Also, even before menopause, as women age, so too do their eggs.  As a result, they are less likely to successfully conceive and produce a live, healthy offspring.[ix]

These biological facts make it impossible for Hagar to be Keturah.

Keturah produced six (6) healthy son to Abraham (Gen. 25:2) over a period of no more than 15 years (as argued in the next blog, “KETURAH – Abraham’s 3rd round of fatherhood”) with at most on average 2 ½ years between each birth.

A very heavy reproduction rate – especially when one takes into account the 9 months of pregnancy when a female is infertile.

This is a testament to the extreme fecundity and biological youth of Abraham’s new wife: a fertility which only a very young, nubile Keturah would possess.

Again, Hagar is not Keturah.

Those who equate Keturah with Hagar ignore the realities of female biology and menopause, and simply have not done the age math above.

Hagar would have been too old to even remotely produce one or two offspring let alone six healthy ones as Keturah did.

 

Ibn Ezra, Radak and Rashbam -- and Sefer HaYashar -- got it right.

Peshat rules.
