Joshua 3:14-4:7

14So when the people broke camp to cross the Jordan, the priests carrying the ark of the covenant went ahead of them. 15Now the Jordan is at flood stage all during harvest. Yet as soon as the priests who carried the ark reached the Jordan and their feet touched the water’s edge, 16the water from upstream stopped flowing. It piled up in a heap a great distance away, at a town called Adam in the vicinity of Zarethan, while the water flowing down to the Sea of the Arabah (that is, the Dead Sea) was completely cut off. So the people crossed over opposite Jericho. 17The priests who carried the ark of the covenant of the LORD stopped in the middle of the Jordan and stood on dry ground, while all Israel passed by until the whole nation had completed the crossing on dry ground.

1When the whole nation had finished crossing the Jordan, the LORD said to Joshua, 2“Choose twelve men from among the people, one from each tribe,

3and tell them to take up twelve stones from the middle of the Jordan, from right where the priests are standing, and carry them over with you and put them down at the place where you stay tonight.” 4So Joshua called together the twelve men he had appointed from the Israelites, one from each tribe, 5and 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, 6to serve as a sign among you. In the future, when your children ask you, ‘What do these stones mean?’

7tell 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.”
