Joshua 4:1-11

So it was when all the nation had finished crossing the Jordan, the LORD said to Joshua, “Take for yourselves the twelve men [chosen] from among the people, one man from each tribe, and command them, ‘Pick up for yourselves twelve stones [one each] from here out of the midst of the Jordan, from the place where the priests’ feet are standing firm; carry them over with you and lay them down at the place where you will spend the night tonight.’ ” Then Joshua called the twelve men whom he had appointed from the sons of Israel, one man from each tribe; and Joshua said to them, “Cross over again to the ark of the LORD your God into the midst of the Jordan, and each of you take up a stone on his shoulder, according to the number of the tribes of the sons of Israel, so that this may be a sign among you; when your children ask later, ‘What do these stones mean to you?’ then you shall say to them that the waters of the Jordan were cut off before the ark of the covenant of the LORD; when it crossed the Jordan, the waters of the Jordan were cut off. So these stones shall become a memorial for Israel forever.” So the [twelve men chosen from the] sons of Israel did as Joshua commanded, and took up twelve stones out of the midst of the Jordan, according to the number of the tribes of the sons of Israel, just as the LORD had spoken to Joshua; and they carried them over with them to the place where they were spending the night and put them down there. Then Joshua set up [a second monument of] twelve stones in the midst of the Jordan at the place where the feet of the priests who carried the ark of the covenant were standing, and they are there to this day. For the priests who carried the ark were standing in the midst of the Jordan until everything was finished that the LORD had commanded Joshua to tell the people, in accordance with everything that Moses had commanded Joshua. The people hurried and crossed [the dry riverbed]; and when all the people had finished crossing, the ark of the LORD and the priests crossed over in the presence of the people.
