The Day that Rav Chaim Served in the IDF

During the week of shiva for Rav Shmuel Grossbard zt”l, Rav Chaim Kanievsky came in to be menachem avel.
After a few moments he turned to the family and said something that stunned everyone in the room.
“You have no idea why I troubled myself to come console you. I have hakoras hatov for your father, who was my commander in the army and helped me a lot.”
Those present were shocked.
Rav Shmuel Grossbard was the father of one of the mashgichim in Ponevezh Yeshiva, but no one had ever heard such a story about him before — and certainly not about Rav Chaim Kanievsky.
One of those present finally asked, “The Rov was in the army!? We never heard this before about our father — and about the Rov even more so!”
Rav Kanievsky smiled and related to them:
“It was during the War of Independence. I was then learning in the Yeshiva of Lomza in Petach Tikvah. The war started and everyone was drafted into the army—with no exceptions. Of course, we knew nothing, until one day a large vehicle pulled up outside the yeshiva and they said that everybody had to get in to go protect the country.
“Because none of us knew how to hold a gun, they gave us sticks and stones and put us out to guard a large hill. I remember everyone was very scared, and Rav Berel Povarsky hid in a bathroom and got out of it. But Rav Moshe Soloveitchik and I—we went, and he was sitting beside me the whole time saying Tehillim while crying.
“Your father, z”l, was appointed commander because he was the oldest in the group. Because he was commander, he got the largest stick.
“When we got there, I asked him what we should do. He told me, ‘You should go up the hill and sit and learn where they can’t see you, but take a stick and two stones so that if the Arabs come, you can scare them away.’ We sat there for a long time, and after we left the place, we were told the Arabs had shot at that same place.”
When he finished relating this story, Rav Chaim said, “Out of gratitude for then, I have come to console you.”
I first saw this story fifteen years ago. It’s made its rounds online a number of times, and been taken down just as many.
There are Charedim who use it to illustrate how yeshiva bochurim could have been involved in the IDF if they were not forced to become secular. Religious Zionists have shared it to call out the Charedim of today for not following in the footsteps of even their teachers.
Perhaps you have a take on this story as well.
But I am not sharing it as a commentary on Charedim, chayalim, or the IDF.
I’d like to take a moment to reflect on how far we’ve come.
It has been 78 years since Rav Chaim sat on a hilltop with sticks, stones, and a Gemara. And in the past two weeks, the IDF has been systematically destroying the last remnants of the Persian Empire. From sticks and stones to AI and air dominance in the Middle East.
From hiding and saying Tehillim, to rewriting the future of Klal Yisrael and the world.
None of this is normal. None of this should even be possible.
No nation has ever risen from the ashes like Klal Yisrael. No exiled people have ever returned home. And never in the history of humanity has a nation achieved so much with so little.
But we should not be surprised.
The pasuk tells us about the completion of the Mishkan:
וַתֵּכֶל... וַיַּעֲשׂוּ בְּנֵי יִשְׂרָאֵל כְּכֹל אֲשֶׁר צִוָּה ה’ אֶת־מֹשֶׁה כֵּן עָשׂוּ
Thus was all the work of the Tabernacle of the Tent of Meeting finished; and the children of Yisrael did according to all that Hashem commanded Moshe—so they did.
The Agra D’Kallah asks: What new information is this pasuk teaching us? Everything has already been built and completed.
It must be, then, that the Torah is revealing the wonder of what had just happened.
A group of pagan slaves rose up, broke free from their psychological bondage, and constructed a home for Hashem in this world. The more they felt the drive to continue, the greater their siyata d’Shmaya.
Rav Charlap explains that just as we were freed from the physical constraints of servitude, we will also free ourselves from the spiritual shackles of exile. We will expel every trace of the twisted thinking we absorbed during our long years of darkness.
In the past few days, Hashem has given us a glimpse into the possibilities awaiting us.
There are higher mountains ahead and greater challenges still to come.
But seventy-eight years ago, Rav Chaim Kanievsky sat on a hill with a stick, two stones, and a Gemara.
That was the army of the Jewish people.
Today we command satellites, fighter jets, intelligence networks, and technologies that reshape the battlefield of the Middle East.
But the truth is, then and now, our strength was never the stick or the stone. It was our connection to the Source of Newness. The Great Power of Chiddush – knowing that Hashem can change everything.
Something new is happening in our world. We are writing the next chapter. May we merit to see it through to the end.
