We're now in a pasuk in Yirmiyah, 32,37 הִנְנִ֤י מְקַבְּצָם֙ מִכׇּל־הָ֣אֲרָצ֔וֹת אֲשֶׁ֨ר הִדַּחְתִּ֥ים שָׁ֛ם בְּאַפִּ֥י וּבַחֲמָתִ֖י וּבְקֶ֣צֶף גָּד֑וֹל וַהֲשִֽׁבֹתִים֙ אֶל־הַמָּק֣וֹם הַזֶּ֔ה וְהֹשַׁבְתִּ֖ים לָבֶֽטַח׃ Behold, I shall gather them back from all the lands to which I've dispersed them in My anger, in My wrath, and in great fury. I will return them to this place, and I will cause them to dwell in security. They will sit there in a secure bitachon atmosphere. This pasuk has a very interesting background, and a very important lesson. At the beginning of this perek, the enemy is surrounding Bnei Yisrael, even using battering rams to get in. But Hashem tells Yirmiyah to buy a field; to make a contract, seal it, sign it and put it in an earthenware vessel so that it will last for a long time. God is saying, ‘ Real estate is going to be good in this land. ’ Yirmiyah says, I don't get it. In pasuk כד he says, “ Behold the rams, they have come to the city to capture it. And the city is being delivered to the hands of the Kasdim who are attacking, due to the sword, the famine of the pestilence. What you declared has happened and You see. Yet You say to me, ‘Buy a field for yourself with money and designate witnesses,’ while the city is handed over to the Kasdim?” Yirmiyah is scratching his head, What's going on here? You promised You would destroy the city, and it’s happening. And I'm supposed to buy a field? Hashem replies, “ Can anything be hidden from Me? Hashem tells him that in the end (and this is our pasuk), Don't worry Yirmiyah, I'm going bring them all back- הִנְנִ֤י מְקַבְּצָם֙ מִכׇּל־הָ֣אֲרָצ֔וֹת It might look bleak now, but it will turn around. Although this land caused Me anger, I'm going to bring everything back. So buy real estate now. It's going to go up. We will return. That's a very powerful bitachon lesson- when the world seems to be crashing down around you, God can do anything. He can turn things around. That's what Hashem was telling Yirmiyah. What's the Halacha L’Maaseh from this story? Legend has it that when Rav Yosef Shlomo Kahaneman, known as the Ponovezher Rav, escaped from Nazi Europe, his city of Ponovezh was destroyed (That's where he got the name.) He came to Eretz Yisrael , and stood on the sand dunes of Bnei Brak. The Nazis were threatening to invade Yerushalayim and the Ponovezher Rav was buying land. They asked him, “ The Nazis are getting close. What are you doing? Why are you buying land?” He quoted this story from Yirmiyah and said, “ Jews buy real estate when the enemy is surrounding. We know Hashem's promise will come true. We will come back.” With that Emuna and Bitachon, he bought the land for the Ponevezh Yeshiva. It’s been said that for many years thereafter, Ponovezh Yeshiva was self-sufficient based on the land that the Ponovezher Rav bought when real estate was down. *We can't mention the Ponevezher Rav without quoting his famous line. When people asked him about this real estate purchase in the middle of a war, he said, “ I might be dreaming but I'm not sleeping.” Which means it's not enough to have a dream, like the famous, ‘I have a dream,’ speech. He didn't just dream, he acted on it. He believed in what he was doing, and he did it.
