Joshua 4:21 tells us that Israel’s stones at Gilgal were meant to prompt questions, so that parents would have a ready opening to tell their children what the LORD had done for them. The stones are a memorial, and their purpose is to lead future generations to ask and to hear the story of God’s faithfulness at the Jordan River. Joshua speaks these words to the people of Israel just after they crossed the river on dry ground and set up twelve stones from its bed.
He spoke to the children of Israel, saying, “When your children ask their fathers in time to come, saying, ‘What do these stones mean?’

What Joshua 4:21 Means
The verse begins with Joshua speaking to the whole nation, which signals that this is a matter for every household and not only for the leaders. He anticipates a future moment when a child looks at the stones and asks, “What do these stones mean?” The question is not a challenge but a natural curiosity, and Joshua expects it. He builds the expectation into the memorial itself.
The phrase “in time to come” points forward. Joshua is not describing a question that will be asked next week but one that will arise after the present generation has passed through the wilderness and settled in the land. The stones are designed to outlast the moment of crossing and to keep the memory alive when the people who saw the miracle are gone.
The verse does not promise that every child will ask or that every family will tell the story well. It describes a practice and its intent. What it promises, by implication, is that God’s acts are worth remembering and that remembering them is a responsibility passed from parent to child.
The Context of Joshua 4:21
The book of Joshua is traditionally attributed to Joshua himself, though the text also includes later notes and was likely compiled and edited over time. It recounts Israel’s entry into Canaan after the death of Moses, and its first audience would have been the Israelite community that lived in the land and needed to understand how they came to possess it. The events at the Jordan are presented as a second Exodus, a deliverance that echoes the crossing of the Red Sea.
Just before verse 21, the priests carrying the ark step out of the riverbed, and the waters flow back over the banks. Verse 20 tells us the stones were set up at Gilgal, a place where the people encamped. Verses 22 to 24 then give the answer parents are to give: the LORD dried up the Jordan so that Israel could cross, just as he dried up the Red Sea, so that all the peoples of the earth would know his power and Israel would fear him forever. Read in this setting, the stones are not random decoration but the first piece of a teaching that the next generation is meant to receive.
Key Phrases in Joshua 4:21
Deuteronomy 6:20-21
20 When your son asks you in time to come, saying, “What do the testimonies, the statutes, and the ordinances, which the LORD our God has commanded you mean?” 21 then you shall tell your son, “We were Pharaoh’s slaves in Egypt. The LORD brought us out of Egypt with a mighty hand…

This passage describes a child asking about the statutes of the LORD and a parent answering by recounting the deliverance from Egypt. It is closely parallel to Joshua 4:21, showing that the practice of answering a child’s question with the story of God’s acts was a deliberate pattern in Israel’s teaching.
Psalm 78:4
We will not hide them from their children, telling to the generation to come the praises of the LORD, his strength, and his wondrous deeds that he has done.

The psalmist speaks of not hiding the works of the LORD from the next generation but telling them to children. It expresses the same commitment to passing on God’s praises and deeds, and it extends Joshua’s instruction into a broader vision of faithful testimony across the ages.
A Short Prayer From Joshua 4:21
Lord, thank you for the stories of your faithfulness that you have given us to remember. Help me to notice the moments in my life where you have acted, and give me the courage to speak of them honestly. Where I have stones of memory, make them a witness to the people I love. When the children in my life ask what these things mean, give me words that point them to you, and let them grow up knowing that you are mighty and worthy of trust. Amen.
