Shared ground
Joshua explains the meaning of the memorial stones in a way that is easy for children to repeat: Israel crossed the Jordan “on dry land.” The stones are meant to spark questions, and the answer is meant to pass on a concrete story, tied to a real place.
The passage credits the crossing directly to : he “dried up” the river until everyone had finished crossing. Joshua also connects this event to the earlier story of the Red Sea, treating both as part of the same pattern of God rescuing and leading Israel.
Joshua states two purposes for remembering and retelling the event. One purpose looks outward: other peoples are meant to learn that Yahweh’s “hand” (his active power) is mighty. The other purpose looks inward: Israel is meant to “fear Yahweh…forever,” meaning an ongoing stance of serious respect and loyalty.
Where interpretation differs
How wide is “all the peoples of the earth”? Some take the phrase as literally global, pointing to a broad, universal horizon: what Yahweh does for Israel is meant to become known far beyond the region. Others take it as a common ancient way of speaking that means “all kinds of peoples” or “people everywhere around us,” without requiring that every nation on the planet will hear about it.
What does “fear Yahweh” most stress? Readers generally agree it is not simple terror. Some think the emphasis falls mostly on awe and reverence in worship; others think it leans more toward loyal obedience; others highlight ongoing trust shaped by remembering what God has done. The text itself holds these close together by linking “fear” to remembering Yahweh’s mighty acts.
Why the disagreement exists
The wording is brief and somewhat broad (“all the peoples of the earth,” “fear…forever”), and the passage is giving a purpose statement rather than spelling out details. Also, the text uses familiar physical-language imagery (“hand…mighty”) that communicates real power without explaining exactly how that knowledge spreads or exactly what the ongoing “fear” looks like in daily life.
What this passage clearly contributes
Explicitly, the passage gives a model of memory and teaching: a visible sign leads to a child’s question, and the parent’s answer anchors identity in a remembered act of God (Jordan dried up; crossing completed). It also frames that act as continuous with earlier salvation history (Red Sea) and states two aims of the memorial: public recognition of Yahweh’s power and Israel’s lasting reverence.
