Moshe's pleas

At the beginning of this week's parsha, Moshe mentions that he pleaded with HaShem to allow him to enter Eretz Yisroel but to no avail. The sefer M’galeh Amukos says that Moshe Rabbeinu davened 515 times - the gematria of Vaeschanan. R' Yehonasan Eybeschutz, in Divrei Yehonasan, is curious to discover how such a tally is reached.

He offers the following possibility: The Midrash states that Moshe Rabeinu started davening on 15 Av. As the gemara (Bava Basra 121a) explains, it was on this day that it was realized that the punishment for the sin of the spies was complete and no more men would die in the midbar. He saw that that decree had been fulfilled and had a glimmer of hope that perhaps, since he had been spared from the decree, he was in a position to plead for Divine Mercy. (This would explain why he never engaged in such extensive prayer on Aharon's behalf as Aharon died prior to 15 Av.)

There are 6 months from Elul to Shevat. We may assume that it was a normal year, whose months alternate between 29 and 30 days throughout. So those full months would total 177 days (3x30 + 3x29). Add the 16 days of Av that Moshe davened and the 7 days of Adar until he dies and we have 200 days. Of those 200 days, 28 are Shabbosos on which it is not permissible to make personal requests. That leaves 172 days. Considering Shacharis, Mincha and Maariv and we now have 172x3 = 516 tefilos. Only off by 1. However, the nation only discovered in the morning of the 15th of Av that the dying has stopped. Therefore, Moshe would have missed the Maariv from the night before and only begun davening at Shacharis. And there you have exactly 515 tefilos!

The Tur writes that on Yom Kippur one is permitted to make personal requests, but on Rosh HaShanah, Sukkos, or Shmini Atzeres it is forbidden. We would then have to subtract three more days of prayer. However, we are taught that Moshe Rabbeinu died on Shabbos. If that is the case, then Rosh HaShanah, Sukkos, and Shmini Atzeres of that year all fell on Shabbos as well. So we need not subtract for them and we are safe with our tally of 515!

Special thanks go out to R' Ari Storch for providing me with the material for this shtikle.

Gematrias off by 1

One of the favourite, and often entertaining forms of drashos is the gematria, finding a significance in the numerical value of a word or group of words. The Steipler Rav devoted the back of his sefer, ברכת פרץ, to gematrios on the parsha that can blow the mind. These aren't simply one word equaling another. Time after time he will find a phrase in the Torah having equal numerical value to the phrase that Rashi uses to explain it. One of the well known rules of gematrios is that it is allowed to be off by one. What the deeper reason is for this, I do not know. However, in the הקדמה to the לקט יושר, a fascinating proof to this concept is brought from the gemara, in the name of the תרומת הדשן. It is not only pertinent to this week's parsha, it is also connected to Tisha B'Av which we  recently commemorated, hopefully for the last time.

The reading for the morning, taken from this week's parsha, begins (4:25) "When you have children and grandchildren, and you dwell long in the land..." the pasuk goes on to explain that Bnei Yisrael will commit grave sins. And HaShem vows that Bnei Yisrael will subsequently be wiped out. The gemara (Gittin 88a and Sanhedrin 38a) learns from a pasuk in Daniel 9:14 "HaShem hastened the calamity and brought it upon us, for HaShem our God is just in all His deeds..." Is it because HaShem is just in all His deeds that he brought calamity upon us? The gemara explains that if Bnei Yisrael had dwelled in Eretz Yisrael for the numerical value of the word "venoshantem" (and you will dwell long), 852, then HaShem would have had to fulfill "avod toveidun," you shall surely perish. However, from the time that Bnei Yisrael entered Eretz Yisrael until they were exiled was only 850 years. HaShem graciously exiled us early so that we would not be doomed to being wiped out. The question is, if HaShem was being so gracious, why didn't He at least wait one more year? It must be, therefore, that 851 would have been considered equivalent to 852 and HaShem therefore had to exile us two years before. From here we see that a gematria may be off by one.

Splitting up the Animals

Some time after the victorious military campaign against Midyan, ל"א:כ"ה-מ"ז, all of the booty - humans and animals - is counted and divided in two. One half is designated for the soldiers who fought the war and the other half is for the rest of בני ישראל. Of the half that went to the soldiers, one out of 500 was to be given to אלעזר. Of the half that went to the rest of the nation, one out of 50 was given to the לויים.

There are a number of puzzling nuances in this chapter. First the totals of the sheep, cattle, donkeys and humans are tallied. Then the halves to the soldiers are counted as well as אלעזר's portion. The halves to the rest of the nation, although exactly the same as the halves to the soldiers are counted. It is recounted that משה distributed the portion for the לויים but no count is given. Lastly, אלעזר's portion is said to be "from the humans, from the cattle, from the donkeys and from the sheep." The same phrase is repeated with regards to the portion of the לויים but the words מכל הבהמה, from all of the animals, is added.

נצי"ב, in העמק דבר, suggests that מכל הבהמה includes other species of animals that were brought back that were fewer in number. Since they were fewer than 1000, there would not have been enough to give אלעזר even one. Therefore, this phrase is left out of the command of אלעזר's portion and these animals' numbers are not significant enough for the תורה to recount.

A fascinating approach is offered in the name of ר' שלמה הכהן מווילנא. Elazar's portion is referred to in פסוק כ"ט as a 'תרומה לה. One of the laws of תרומה is that one may not separate from one species as תרומה for another. Therefore, אלעזר's portion was required to be one out of every 500 of each animal. However, this was not a requirement with the portion of the לויים and it was sufficient to give them 1/50 of all the animals combined. That is the meaning of מכל הבהמה. The לויים were given 1/50 of all the animals. And that is why the תורה does not go into any detail concerning the division for it was not exact.

No Population Increase

I was discussing the census numbers with someone one שבת. An interesting question was posed regarding the lack of an increase in population over the different censuses that were taken throughout the years in the מדבר. This question is really better suited for פרשת פינחס which takes place towards the end of their journey with still no increase. 

One obvious question is that there should have been many children born over the course of the first 20 years in the מדבר who would be counted by the last census. I've heard some answers to that question which I'd rather not go into at this juncture. The less obvious but more difficult issue is the children that came out of מצרים. As we've pointed out in a previous post, the first born made up approximately 4% of the population which means each family was exceedingly large. It would probably be a gross understatement to suggest that each family consisted of at least 10 male children. Let's even go so far as to say 5, to take into account children who were already counted in the original census. Even though the original 600,000 included a number of different generations it still seems that by all accounts, there should have already been millions of male children not counted in the first census. So where did all these millions go?

The Probability of the Goral

In pasuk 26:54, the Torah explains how the land was divided amongst the tribes. Rashi explains exactly how the lots were picked to determine each tribe's portion.

Even though the portions were Divinely predetermined, a lot-drawing process was used to assign each tribe their portion. Rashi explains that one drum was filled with 24 pieces of paper. On 12 pieces of paper were written the names of the 12 tribes. On the other 12 were written the 12 portions that were to be assigned to the tribes. Each Nasi approached the drum and picked out two pieces of paper. One paper had the name of his tribe written on it and the other the prescribed portion of land in Eretz Yisrael. The purpose of this exercise was to prove the Divinity of division plan that allotted each tribe its portion and appease any tribe who felt it might be unfair. As such, I believe that a miracle of this type may be more greatly appreciated if we knew exactly how unlikely it would have been to happen naturally.

Suppose we had a prescribed list of which portion was to be assigned to which tribe. What would be the odds of each Nasi picking out both the name of his tribe and also the corresponding piece of land that had already been prescribed? Let us start with the first Nasi. He has 24 pieces of paper to choose from. He must pick two specific pieces of paper out of the drum. The odds of taking the first one correctly would be 1/24 and then the odds of taking the second correctly would be 1/23. However, since the two papers were taken together, the order does not matter. The rules of probability theory state that if the order of the choices is not relevant, than the odds must be multiplied by the number of possible sequences which, in this case, is two. So the odds of the first Nasi picking the right pieces is 2/(24 x 23). With 22 pieces of paper remaining, the odds of the second Nasi picking correctly will be 2/(22 x 21). And so on. The last Nasi's odds will be 2/(2 x 1) which is 1. That means that he will definitely pick the right ones. That is understandable. By the rules of probability theory, in order to find the odds of all the Nesiim picking correctly, we must multiply each Nasi's odds together. Thus, the odds may be generalized as

212

(24 x 23 x 22 x 21...x 2 x 1)

24 x 23 x 22 x 21....x 2 x 1 is referred to as 24 factorial and expressed as 24! Thus the final expression is 2¹²/24!. When all is totalled, the odds of the draw falling out exactly as planned without any Divine intervention would have been one in 151,476,000,000,000,000,000.

This calculation is based on Rashi's explanation in the chumash according to the Midrash Tanchuma. However, Rashi (actually written by Rashbam, Rashi's grandson,) in the gemara (Bava Basra 122a) states clearly that two drums were used. This will alter the calculation somewhat. The first Nasi would have a 1/12 chance of picking his tribe's name from the tribe drum and a 1/12 chance of picking the correct portion from the portion drum. The fact that the order does not matter will not affect the odds in this case because the choices are made from two separate groups. The odds for both drums are multiplied and thus, the first Nasi's odds will be 1/12². The odds of the second Nasi will be 1/11². And so on. The total odds will be:

1

122 x 112 x 102 x 92 x 82 x 72 x 62 x 52 x 42 x 32 x 22 x 12

This can, in fact, be simplified as 1/12!². The final odds will be one in 229,442,532,802,560,000. This is approximately 660 times more probable than the odds according to Rashi on the chumash.

Just to get an idea of the extent of this improbability, the odds of winning the Powerball Jackpot are approximately one in 175 million. That is over 1.3 billion times more likely to happen than this, according to Rashi on the gemara, and over 860 billion times more likely according to Rashi on the chumash. The odds of getting fatally hit by lightning in a given year are approximately 1 in 2.4 million. In fact, it is more likely for one to win the Powerball twice in one week or get fatally hit by lightning two-and-a-half times in one year than for the goral's results to have been produced naturally. This is a veritable testimony to the extent of the miracle that occurred and the Divinity of the apportioning of Eretz Yisroel to the twelve tribes.

תשע"ד: A similar drawing came up this week in דף יומי on :תענית כ"ז regarding the גורל used to determine the order of the משמרות in the בית שני. According to רש"י's understanding, there was a similar miracle at play. The probability associated with that drawing is discussed here.
