We're now in Tehilim 71,5, where David Hamelech says, כִּֽי־אַתָּ֥ה תִקְוָתִ֑י אֲדֹנָ֥י יֱ֝הֹוִ֗ה מִבְטַחִ֥י מִנְּעוּרָֽי׃ You are my hope, Hashem my God, my reliance from my youth. The Ibn Ezra says, ‘ You are my hope ,’ means there's no one else that I count on besides You, from the day I set foot on this earth, The Malbim says, ‘ Tikvati/hope’ means in the future and ‘Reliance from my youth’ means in the past, which means David Hamelech is saying, based on past performance, I know that Hashem is going to give me future success. That's contrary to the typical disclaimers following stock advertisements, such as, “ Past performance is not an indicator of future success.” When it comes to God, past performance is an indicator of future success. This is one of the fundamentals that Hovot Halevavot tells us. In Shaar Bitachon perek ב , the fifth of the seven fundamentals that are needed in order to rely on somebody is that this person is somebody who was exclusively taking care of you from the beginning of your existence throughout your development until your old age. Obviously, there are very few people who have such an intimate knowledge of you. When you find such a person, you can rely on him, based on what he did up until now, that he'll continue to do so. Obviously, this is God. That's what David Hamelech is telling us in this beautiful pasuk. Ki Atah Tikvati/You are my hope. Why? because מִבְטַחִ֥י מִנְּעוּרָֽי /I relied on You in the past and that past reliance gives me hope for the future. There's another pasuk that comes a little bit later in the same chapter where David Hamelech says, פִּי יְסַפ ֵּר צִדְקָתֶך ָ כָּל הַיּוֹם תְּ שׁוּעָתֶך ָ I will speak of your justice all day of how You saved me, כִּי לֹא יָדַעְת ִּי סְפֹרוֹ ת / There is no end. And then he says, אָבוֹא בִּ גְבֻרוֹת אֲדֹנָי יֱהֹוִה אַזְכ ִּ ירצִדְקָתְך ָ לְבַד ֶּךָ: I'll come to my old age (my eighties) and will mention the righteousness that You did, alone . What does this mean? The Chatam Sofer, in his derashot , his sefer of sermons, Shabbat Shuva , when discussing this pasuk, says that anyone that understands Hashgacha Pratit realizes, “ The killing of Vashti was like the splitting of the sea, just nobody recognized it. That's what it means in this pasuk when David Hamelech says, “ When I get old, when I reach my eighties, I’ll look back and mention the righteousness that You did alone. That only you know, that I don't know.” He adds, “ It’s a mitzvah on every person, when he gets older (we'll say from 60 and) to go and look into all the things that happened from his youth until the point he's at now (source included below) and see how different causes brought things about, and tell your children . And they'll also realize the greatness of God in their lives. That's what David Hamelech is saying here. “ God, don't forsake me in my old age, I'm going to tell the future generations. I'll tell my children.” This is extremely important. I'll share a little personal anecdote. Not long ago, my granddaughter in 10 th grade called my wife. She said was given a homework assignment to interview her grandmother about how high school was in the olden days. I didn’t think that I was that old nor that was my wife was olden . But believe it or not, we’re a little older than we think. We have children, we have grandchildren, we have life experiences, and we can share it with them. My wife spoke about how much homework they had, and I jokingly added, “ Remember, it was very hard in those days because we only had quills. We didn't have pens in those days.” She actually took us seriously for a moment! But we're older than we think. We have more experience than we think. If we look back, we have enough stories to tell our children and grandchildren. And we can say this pasuk with confidence, Ki Atah Tikvati/ You are my hope. Why? מִבְטַחִ֥י מִנְּעוּרָֽי Because I've been relying on You from my youth. You have a track record. And past performance is an indicator of futu
