Before you is the full lesson delivered on the Holy Shabbat of Parshat Vayechi 5786 by the esteemed tzaddik Rabbi Eliezer Berland shlit"a, during Kiddusha Rabba after the conclusion of the Mussaf prayer:

The lesson is written as understood by the listener, and if there is an error, it should be attributed to the writer and not God forbid to our teacher the Rav shlit"a

Once there was one, called Sisai. She jumped off the roof. Why did she jump off the roof? She committed suicide literally, jumped off the roof, jumped off the roof. She apparently was Shuvu Banim… So why did she jump off the roof? Bring a Gemara Bava Batra. So the Gemara on page 3 says that Herod killed all the house of the Hasmoneans, and only one girl remained, and she went up to the roof and jumped and said: Whoever comes and says he is from the house of the Hasmoneans – then he is a slave. And this is also a Gemara in Kiddushin page 70: The Gemara says: Whoever claims he is from the house of the Hasmoneans – he is a slave, because Herod killed all the house of the Hasmoneans, and only one girl remained, and she also jumped off the roof and died.
Then Shmuel arrived in Nehardea, and he expounded on this and said that there are many who are slaves here. Then they came to stone him with stones. From here it is proven that they were Shuvu Banim, because they lifted giant stones to throw at Shmuel. Then he said to them: If you are silent – then fine, but if not, I will declare upon you that you are all mamzerim. Then they immediately put down all the stones and threw them into the river, and they blocked the river with it. Pashchur had four hundred slaves or four thousand slaves, and they all assimilated into the families of the priesthood. They all married kohanot, they assimilated into the families of the priesthood.
And why did this happen to the house of the Hasmoneans that they were all annihilated? Says the Ramban on our parsha. Why were all the house of the Hasmoneans annihilated? Because they took the kingship, and they were not from the house of David. On the verse 'The scepter shall not depart from Judah' (Genesis 49:10), that the kingship can only be for someone who is from the house of David, and they were not from the house of David. It was forbidden for them to take the kingship.
So only someone from the house of David can take the kingship. 'The scepter shall not depart from Judah', and therefore they were punished that nothing remained from the Hasmoneans, even though they were tzaddikim, because it was forbidden for them to be kings.
Now this is 'Shabbat Chazak'. Chazak in gematria is Moshe. How is Chazak in gematria Moshe? Because Chazak is 115, and Moshe is 345. So how is this gematria Moshe?
It is arranged, like Karkar in gematria Peah. 'And Karkar all the sons of Sheth' (Numbers 24:17). How is Karkar in gematria Peah? Karkar is six hundred. Every Peah is three hundred, because Peah is 86. So this is gematria six hundred – Karkar. So how is this Peah? Says the Arizal: Peah in gematria is 86, which is Elokim. And Elokim in full spelling is gematria 300: Alef Lamed Heh Yud Mem – gematria three hundred. Doubled – two Peahs – this is six hundred, gematria Karkar.
So how is Moshe in gematria Chazak? Because Chazak (115) Chazak (115) is twice, so this is 230. And strengthened – so there is another Chazak (115) in the word and strengthened. So three times Chazak (115 X 3 = 345) is gematria Moshe. And remains 'and nit' – so and nit, and the kuf is Yosef, and the tav hints that it illuminates below ten tefachim. Yosef illuminates below ten tefachim.
So Chazak Chazak and strengthened – gematria Moshe Yosef.
So it is written in the parsha: 'And went up with him also chariots and horsemen' (Genesis 50:9). Why did Yosef take horsemen to the funeral? Horsemen means tanks, means MIGs. Since when do you take tanks to a funeral? Going to a funeral – take tanks? Rather, Yosef was preparing for a world war. He was preparing that there was going to be a world war at the funeral of Yaakov, and Tzfo came to fight with him – Tzfo son of Eliphaz, because Esau did not want to give up the Cave of Machpelah.
The Arabs to this day are not willing to give up the Cave of Machpelah. Thanks to Shuvu Banim – this is open, also the Cave of Machpelah and also the Tomb of Rachel is open today. Thanks to Shuvu Banim. This was in the year 5743, when we said to travel for a whole week – every day a hundred people, twenty vehicles, twenty-five vehicles. And we traveled every day. When we got there, we saw a convoy of UN vehicles, but we did not know what they wanted. We saw them, we saw the convoy of UN vehicles standing there. After that, it became clear that they came to see if Jews were coming there or if it was possible to bring it to the Waqf, to the Arabs. Because they said that Jews do not come there. And then they came to see, and they saw that for a whole week every day a hundred people come there. So they decided that it is not possible to transfer it to the Arabs.
And also the Tomb of Rachel – Shuvu Banim opened it. They would go through the shootings with babies on their shoulders. Nachman [Zucker] took Naftali on his shoulders, and also Ben Sasson took his Naftali on his shoulders. And they went through the shootings, and the Arabs were shooting because they thought it was soldiers, and the soldiers were shooting because they thought it was terrorists. And they ran through the shootings. After that, they found an entrance from behind the tomb, so they entered from there. And suddenly they heard screams outside. Then they came and saw that they had entered. Then they saw that they were not willing to give it up, and they had to open it.
So there was a war with Tzfo over Hebron. January – this is named after Tzfo. The Abarbanel says in chapter 35 that January is named after Tzfo, because there is Jaguar – this is a leopard, a tiger. We went into the jungles, we went to look for tigers, but we did not find them. Apparently, they heard that Shuvu Banim arrived – so they fled. Tiger is a lion. The Gemara says in Chullin 59: Tiger is a lion. The Gemara says: Tiger is the lion of the upper house, that he wanted to see a lion.
Now Yehuda Schwartz showed me a novelty that I had not seen. I do not know how I had not seen this until today. It is written in the Targum in Divrei Hayamim (1 Chronicles 11:22) that Benaiah son of Jehoiada, who struck the lion in the pit on a snowy day – this was on the tenth of Tevet. He killed it in the pit, and the novelty is that in the pit there is no place to fight, and despite this, he defeated it. So this was on the tenth of Tevet. Now Yehuda Schwartz showed me this: Why on the tenth of Tevet? Why not on the seventeenth of Tammuz? Why not on the ninth of Av? So writes the Targum in Divrei Hayamim. The Targum Rav Yosef on Divrei Hayamim (chapter 11 verse 22), says: When did he kill the lion – this was on the tenth of Tevet.
So Tzfo, when he became king in Rome, he conquered Rome. The city of Genoa – this is after his name, after the name January, which is Tzfo. So he came to fight, not to allow the burial of Yaakov. And then they captured him and put him in prison for eighty-one years.
