Inflation and the Price of the Cave of Machpelah
Prof. Daniel Sperber
Dept. of Talmud
In the time of the patriarch Abraham coins had not yet come
into use. They were only invented in the eighth century B.C.E., and the "four
hundred shekels of silver" (Gen. 23:16) that Abraham gave Ephron the Hittite was
actually a certain weight of silver. In the time of the Sages, however,
an attempt was made to translate this weight into monetary value in terms of the
current coinage of the day. As we read in the Jerusalem Talmud,
As R. Haninah said: Every time shekels are referred to
in the Torah it means selas, in the Prophets litra, and in the
Writings kintirin. Rabbi Judah bar Pazi said: Except for the shekels of
Ephron, which were kintirin. How do we know this? Because it says "Let
him sell it to me, at the full price" (Gen. 23:9).
R. Judah (son of R. Simon) ben Pazi, a famous homilist,
belonged to the third-fourth generations of amoraim. According to his
remark above, made in the fourth century, the price of the cave of Machpelah was
four hundred kintirin. But how much were kintirin worth? This is
a known coin, the centenarius (see Sperber, Roman Palestine 200-400, Money
and Prices, 1974, p. 166) worth around 10,000 dinars. Thus, it follows from
his remark that the price of the cave of Machpelah was 4 million
On the face of it, 4 million dinars seems an exaggeratedly
large sum to have been charged for a field and a double cave! But actually,
this is not so, for we noted that R. Judah's remark was made in the first half
of the fourth century, at a time of rampant inflation. We know this to have
been true from several inscriptions discovered from this period: the tomb
inscription at Mjedil, indicating that its price was 5,000,000 dinars, or the
building at Kharsan, which cost 50,000,000 dinars.
Various homilies of the Sages also contain indications of
these hard times. For example, Exodus Rabbah 2.9: "'How much is this
[gem]?' 'A million [dinars],' he answered. 'And how much is the bigger one?'
It is hard to determine exactly when R. Judah ben Pazi's
remark was made, insofar as this period was marked by great fluctuations in
prices and even differences in rates from place to place. To a certain extent,
however, we can narrow down the possibilities, arriving at a fairly good
approximation. On one hand, there is a tendency in the writings of the Sages to
view the cave of Machpelah as a place which cost Abraham dearly (see Bava
Mezia 7a). Therefore, we can say that in the era under discussion a sum of
4 million dinars for a field and a double cave was quite a stiff price. On the
other hand, in the Jerusalem Talmud, Ma'aser Sheni 1.2, we have R.
Jonah asking: "If a person's wallet were to fall into a well, and there were a
million [dinars] in it, and by spending half a million he could recover the
wallet, is it as if he has in his possession the half million?"
Needless to say, R. Jonah's words were said quite some time
after the remarks by R. Judah ben Pazi, since according to R. Jonah a million
dinars was a relatively small amount of money, such as might be carried by a
person in his wallet, whereas according to R. Judah it was quite a considerable
amount of money.
It seems that R. Jonah's remark was made in the 60's of the
fourth century. Presumably R. Judah ben Pazi's words were said earlier, perhaps
in the 40's of the same century, when four million dinars was a reasonable sum.
Moreover, in the next decade or two there was a sharp decline in the value of
the currency, to the extent that a million dinars became almost a negligible
sum, and this devaluation of the currency led to a sharp rise in
In the interpretation of R. Judah ben Pazi the homilist sought
to translate the biblical price of "four hundred shekels of silver" into the
monetary terms of his day, terms that would have concrete meaning to his
audience. In his computations the homilist seems to have relied on current
prices in the country in order to arrive at the price paid for the cave of
Machpelah: four million dinars.
