יהושע, פרק ד׳, פסוק כ״א

Setting up a monument of stones acts as a powerful educational tool designed to spark curiosity and keep historical memory alive. The purpose of building this structure is twofold. It is not meant to be a sign solely for the people living in the present time, but it is specifically constructed to stand as a lasting memorial for all the generations to follow [מלבי״ם].

The expectation that children will ask about the monument applies equally to the young ones alive at that very moment and to those who will be born in the future [רד״ק]. Their questions will naturally arise because the structure is designed to stand out. It is not a random pile of rocks or the remains of a ruined building. Rather, it is carefully arranged from a specific number of large, freestanding stones. This distinct and prominent setup naturally captures the attention of children, prompting them to wonder and ask about its historical meaning [ביאור שטיינזלץ].
