Joshua 4:5-7 Amplified Bible, Classic Edition (AMPC)
5 And Joshua said to them, Pass over before the ark of the Lord your God in the midst of the Jordan, and take up every man of you a stone on his shoulder, as is the number of the tribes of the Israelites,
6 That this may be a sign among you when your children ask in time to come, What do these stones mean to you?
7 Then you shall tell 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 Jordan were cut off. So these stones shall be to the Israelites a memorial forever.
Joshua 4:5-7 New International Version (NIV)
5 and said to them, “Go over before the ark of the Lord your God into the middle of the Jordan. Each of you is to take up a stone on his shoulder, according to the number of the tribes of the Israelites, 6 to serve as a sign among you. In the future, when your children ask you, ‘What do these stones mean?’ 7 tell them that the flow of the Jordan was cut off before the ark of the covenant of the Lord. When it crossed the Jordan, the waters of the Jordan were cut off. These stones are to be a memorial to the people of Israel forever.”
