Joshua 4:5-7

King James Version (KJV)

⁵ And Joshua said unto them, Pass over before the ark of the Lord your God into the midst of Jordan, and take you 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 Jordan were cut off before the ark of the covenant of the Lord; when it passed over Jordan, the waters of Jordan were cut off: and these stones shall be for a memorial unto the children of Israel for ever.
