Joshua 4:5-7

21st Century King James Version

⁵ And Joshua said unto them, “Pass over before the ark of the Lord your God into the midst of the Jordan, and take ye up every man of you a stone upon his shoulder, according unto the number of the tribes of the children of Israel,

⁶ that this may be a sign among you, that when your children ask their fathers in time to come, saying, ‘What mean ye by these stones?’

⁷ then ye shall answer them that the waters of the Jordan were cut off before the ark of the covenant of the Lord: when it passed over the Jordan, the waters of the Jordan were cut off. And these stones shall be for a memorial unto the children of Israel for ever.”
