We are now in Yeshaya 50,10: מִ֤י בָכֶם֙ יְרֵ֣א יְהֹוָ֔ה שֹׁמֵ֖עַ בְּק֣וֹל עַבְדּ֑וֹ אֲשֶׁ֣ר ׀ הָלַ֣ךְ חֲשֵׁכִ֗ים וְאֵ֥ין נֹ֙גַהּ֙ ל֔וֹ יִבְטַח֙ בְּשֵׁ֣ם יְהֹוָ֔ה וְיִשָּׁעֵ֖ן בֵּאלֹהָֽיו׃ Who amongst you is God-fearing, who listens to the voice of his servant, who's walking in darkness and there is no light, He should rely on Hashem and lean on his God. In his sefer Or Yechezkel , Rav Yechezkel Levenstein discusses the simple meaning of the pasuk when he talks about Avodat HaBitachon. He says this refers to a man who is in a situation of complete darkness, who doesn’t see any natural hope that can light up the way. He's in a dark tunnel. And with that, he's responsible to rely on Hashem as if the salvation is there already, because that is the essence of bitachon. He says. I'm not relying on the details but of how it's going to happen, because I don't see any way out. I'm relying on Hashem, the One that's able to do everything. I'm looking at the broader picture. Therefore, although my eyes see only darkness, that doesn't make a difference. That's how Rav Chaskel explains this pasuk . Walking in the dark means in the dangers of life. He says that is what bitachon is about. In another place in his book on Emuna, when he talks about the concept that man is born to toil, he says the toil of this world is the toil of Emuna. Again, he refers to a man who's walking in a totally dark situation. In the words of Rav Yehezkiel Levenstein, what's going on around him, has nothing to do with him. Rather, I'm solid in my reliance on Hashem as if I'm not even in a problem. You could talk the talk, but Rav Chatzkel Levenstein walked the walk. He was the one that led the Mir Yeshiva through the Trans-Siberian railroad to Kobe, Japan to Shanghai. They were in the middle of an inferno, and yet they were in an oasis. One of the students reported that when they were in Mir in Europe, they never had never seen oranges in their lives. All they basically had was potatoes. Yet on their escape, they had tourist visas, and because of this, when they got to Moscow, they were well treated. They were taken on tours, brought to a zoo and they were served oranges for the first time. The whole world was falling apart around them, and they were eating oranges! That's Rav Chatzkel Levenstein’s message. In his sefer Darkei Avodah / Ways to Work on Yourself, in an essay entitled, the Greater the Hope, the Greater the Merit, he gives an example of what it means to be in the darkness: It's Erev Shabbat. The sun is setting, and the man has no food for Shabbat, yet he doesn't despair. He has solid reliance. That's the definition of Emuna. I'm in the darkness . This is a pasuk in Micha 7,8: אַֽל־תִּשְׂמְחִ֤י אֹיַ֙בְתִּי֙ לִ֔י כִּ֥י נָפַ֖לְתִּי קָ֑מְתִּי כִּֽי־אֵשֵׁ֣ב בַּחֹ֔שֶׁךְ יְהֹוָ֖ה א֥וֹר לִֽי My enemy should not be happy because although I fell, I got up. Though I'm sitting in the darkness, God is my light. That, says Rav Chatzkel Levenstein, is the definition of bitachon, and that is our pasuk. מִ֤י בָכֶם֙ יְרֵ֣א יְהֹוָ֔ה שֹׁמֵ֖עַ בְּק֣וֹל עַבְדּ֑וֹ אֲשֶׁ֣ר ׀ הָלַ֣ךְ חֲשֵׁכִ֗ים וְאֵ֥ין נֹ֙גַהּ֙ ל֔וֹ יִבְטַח֙ בְּשֵׁ֣ם יְהֹוָ֔ה וְיִשָּׁעֵ֖ן בֵּאלֹהָֽיו / Who is a God-fearing man (as we said in the past, bitachon is a sign of fear of God) Who listens to the voice of his servant. He's walking in the darkness without light (not just darkness, darkness without a flashlight) Rely on the name of Hashem and lean on God. B’Ezrat Hashem, we will continue tomorrow with the Gemara’s explanation of this pasuk.
