Joshua Chapter 4 Verse 3And command ye them, saying, Take you hence out of the midst of Jordan, out of the place where the priests' feet stood firm, twelve stones, and ye shall carry them over with you, and leave them in the lodging place, where ye shall lodge this night.

And Joshua said, Hereby ye shall know that the living God [is] among you, and [that] he will without fail drive out from before you the Canaanites, and the Hittites, and the Hivites, and the Perizzites, and the Girgashites, and the Amorites, and the Jebusites.

Behold, the ark of the covenant of the Lord of all the earth passeth over before you into Jordan.

Now therefore take you twelve men out of the tribes of Israel, out of every tribe a man.

And it shall come to pass, as soon as the soles of the feet of the priests that bear the ark of the LORD, the Lord of all the earth, shall rest in the waters of Jordan, [that] the waters of Jordan shall be cut off [from] the waters that come down from above; and they shall stand upon an heap.

And it came to pass, when the people removed from their tents, to pass over Jordan, and the priests bearing the ark of the covenant before the people;

And as they that bare the ark were come unto Jordan, and the feet of the priests that bare the ark were dipped in the brim of the water, (for Jordan overfloweth all his banks all the time of harvest,)

That the waters which came down from above stood [and] rose up upon an heap very far from the city Adam, that [is] beside Zaretan: and those that came down toward the sea of the plain, [even] the salt sea, failed, [and] were cut off: and the people passed over right against Jericho.

And the priests that bare the ark of the covenant of the LORD stood firm on dry ground in the midst of Jordan, and all the Israelites passed over on dry ground, until all the people were passed clean over Jordan.

And it came to pass, when all the people were clean passed over Jordan, that the LORD spake unto Joshua, saying,

Take you twelve men out of the people, out of every tribe a man,

Then Joshua called the twelve men, whom he had prepared of the children of Israel, out of every tribe a man:

And Joshua said unto them, Pass over before the ark of the LORD your God into the midst of 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:

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?

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.

And the children of Israel did so as Joshua commanded, and took up twelve stones out of the midst of Jordan, as the LORD spake unto Joshua, according to the number of the tribes of the children of Israel, and carried them over with them unto the place where they lodged, and laid them down there.

And Joshua set up twelve stones in the midst of Jordan, in the place where the feet of the priests which bare the ark of the covenant stood: and they are there unto this day.

For the priests which bare the ark stood in the midst of Jordan, until every thing was finished that the LORD commanded Joshua to speak unto the people, according to all that Moses commanded Joshua: and the people hasted and passed over.

And it came to pass, when all the people were clean passed over, that the ark of the LORD passed over, and the priests, in the presence of the people.

And the children of Reuben, and the children of Gad, and half the tribe of Manasseh, passed over armed before the children of Israel, as Moses spake unto them:

About forty thousand prepared for war passed over before the LORD unto battle, to the plains of Jericho.
