Etiology

Parshat Vayetze

Why the book of Bereishit (Genesis) was written, is a question that scholars and rabbis both ask. Prolific medieval commentator Rashi poses it in Bereishit 1:1, offering the option that the Torah should begin partway through Exodus when the first mitzvot are written.  Traditionally, Jewish commentators have attempted to extract moral, and sometimes disastrously, scientific and historical lessons from the various stories.  We will provide one alternative reason for various stories in Bereishit.  We'll note that one reason cannot suffice for all the stories, many of which may have been written at different times for different purposes.  This week we will look at etiological reasons, and next week we will look at another reason, which I'll leave for a surprise.

Etiology, in the context I'm using it, basically means explanations for why things are the way they are, usually with mythical or historical reasons. These are sometimes used to explain why things are named the way they are. For example, Homer describes the naming of the Greek city of Delphi as arising because of the transport of people to the city on dolphins (the actual origin likely has to do with a similar sounding word meaning womb.) Sometimes, these stories are used to explain why certain religious activities are performed. An example here could be the Aztec belief that the sun was a deity that required continual human sacrifice to be sustained or he would fail like the four previous suns did.  The story of the four previous suns gives an etiological reason justifying the current human sacrifice ritual.  Sometimes these explain physical phenomena, an example from the Torah would be the explanation of why rainbows exist at the end of the flood story.

The Torah furnishes lots of examples of etiological stories. These stories are present in pretty much every culture that has provided us with a record of beliefs.  It's not surprising that the ancient Israelites would provide us with their stories also.

The naming of places

In this week parsha, we have etiological examples of place naming. After Yaakov (Jacob) has his famous dream with the ladder to the heavens, he wakes up and says: (Gen 28:17-19),

17 And he was afraid, and said: 'How full of awe is this place! this is none other than the house of God (beth elokim), and this is the gate of heaven.' 18 And Jacob rose up early in the morning, and took the stone that he had put under his head, and set it up for a pillar, and poured oil upon the top of it. 19 And he called the name of that place Beth-el, but the name of the city was Luz at the first.

The Torah tells us how the city of Luz got the name of Beth-el. It's because Yaakov associated it with the house of God, beth elokim.  Beth-el actually gets named a second time, also by Yaakov (Gen 35:7), for a different reason.  And furthermore, it seems to have already had this name by the time Avraham came through (Gen 12:8).

This parsha also informs us of how all the tribes got their names, providing etiological explanations for all of them. Just one example will suffice (Gen 29:32)

And Leah conceived, and bore a son, and she called his name Reuben; for she said: 'Because the LORD hath looked (ra'ah) upon my affliction; for now my husband will love me.'

The name Reuben is explained to derive from the root ra'ah, to look. The other tribes are named similarly.  These etiological origins for names are all over the Torah, sometimes in cases that make no sense.  For example, Moshe (Moses) is a well known Egyptian name, but in the Torah etymology, she is named by an Egyptian princess with a pun that only makes sense in Hebrew.

At the end of the parsha we are given one more example of an etiological naming, the area of Gilead, is explained as to have arisen from the words Gal Ed, literally, monument-witness. This is because Lavan (Laban) set up a monument as a witness for a non-aggression treaty with Yaakov.

Ritual explanations

Unfortunately, this parsha doesn't furnish us with an example of an etiological reason for a ritual, however, next week's does, so we'll look ahead a little.

The story of Yaakov's wrestling with a mysterious man provides us with lots of etiological reasons for things. It gives an explanation of why Yaakov is also known as Yisrael, because he "strove" (saritah) with God (or gods) (elohim). It tells us why the river is called Yavok, because a man "wrestled" (vayeavek) with him. It explains why the place gets the name Penuel, because Yaakov saw God face (panim) to face. And lastly, and relevant to this topic, it explains the religious restriction on not eating a particular part of an animal (32:33).

Therefore the children of Israel eat not the sinew of the thigh-vein which is upon the hollow of the thigh, unto this day; because he touched the hollow of Jacob's thigh, even in the sinew of the thigh-vein.

The beginning phrase of this sentence, here translated "therefore" is in Hebrew al cain, and is often written in the Torah prior to an etiological reason for a specific practice. Similarly the phrase "until this day" is used in a lot of etiological contexts. The simple way to interpret these phrases is something like, "this is the way these things are at the time of writing, and here is why."

Natural Phenomena

Most of the Torah's examples of etiological explanation for natural phenomena occur in the first two parshiot. We learn why it rains from the sky (there's water above that's kept there by a rakiah, a firm boundary). We learn why women have pain during childbirth, and why agriculture is so darn hard. We learn why there are rainbows, and why it's impossible to understand the weird speaking neighbors to the east.  At least we learn the mythological stories that the ancient Israelites invented over the course of many years to explain these things. We actually know the real reasons for these phenomena nowadays, and many religious Jews interpret these stories allegorically, because the etiological explanation have since been proven false. 

There is one example from a recent parsha of a natural phenomenon with an allegorical explanation.  Normally regions surrounding bodies of water are lush areas, full of plant an animal life.  However, the region near the dead sea is the exact opposite, it is completely devoid of life, a barren wasteland.  The sea itself has a salt concentration far higher than what life can thrive in.  How did this region become so?

The Torah's answer was that it once was fertile, just like every other body of water.  But it was wicked and was turned into what it is today as punishment from God, and all the population were killed.  Just like the stories earlier in Genesis, we know today that there was no catastrophic geological behavior in this region in the last 10,000 years.  This is another example of the ancient Israelites inventing explanations for the world around them etiologically.

Understanding the World

Etiology is a manner in which many ancient people used to understand the world.  This is a great human desire from the dawn of time, and it's no surprise that every culture has these kinds of stories.  One question to ask, for people who hold the Torah to have some special divine value, is whether the Israelite stories differ in style or verifiability from the many other stories that have been passed to us from other cultures.  Having read a lot of these stories, it is my opinion that there is no noticeable difference.  However, perhaps you have a different view.  I'd love to hear. 

Next week we'll talk about another, sometimes overlapping reason, for why the book of Bereishit was written.
