My wife’s sister lives with her family in Ramat Beis Shemesh. They are definitely chareidim. They have a neighbor who is not frum at all, whose son was going into the army during the fighting in Gaza earlier this year.
The neighbor told my SIL how she’s nervous for her son, but also proud of what he was doing. My SIL told her children to daven for him. She got the full name of the boy, and gave it to her kids. They also took it to yeshiva, and told their Rebbe what the situation was. The Rebbe told the class that they need to appreciate the soldiers, and daven for their protection. He wrote the name of the boy on the side of the board (don’t know if it was chalk or a whiteboard), and said, “Have in mind that our learning should be a zchus to protect him! If anyone else has names of soldiers, we will add them to the list!”
Every morning after that, the Rebbe would start class by reading the names of the soldiers, and saying out loud that their learning should be a zchus to protect them.
My SIL told her neighbor this, and she broke down crying in appreciation of what they were doing. Showing appreciation causes a great kiddush Hashem!
