The Priests carrying The Ark across the River Jordan on dry ground Painting by James Tissot Jewish Museum, New York
After the death of Moses the servant of the Lord, the Lord said to Joshua son of Nun, Moses’ aide: “Moses my servant is dead. Now then, you and all these people, get ready to cross the Jordan River into the land I am about to give to them—to the Israelites. I will give you every place where you set your foot, as I promised Moses. Your territory will extend from the desert to Lebanon, and from the great river, the Euphrates—all the Hittite country—to the Mediterranean Sea in the west. No one will be able to stand against you all the days of your life. As I was with Moses, so I will be with you; I will never leave you nor forsake you. Be strong and courageous, because you will lead these people to inherit the land I swore to their ancestors to give them." (Joshua 1:1-6)
God gave Joshua instructions in how to cross the River Jordan into the Promised Land.
“When you see the ark of the covenant of the Lord your God, and the Levitical priests carrying it, you are to move out from your positions and follow it. Then you will know which way to go, since you have never been this way before. But keep a distance of about two thousand cubits between you and the ark; do not go near it.”
Joshua told the people, “Consecrate yourselves, for tomorrow the Lord will do amazing things among you.”
Joshua said to the priests, “Take up the ark of the covenant and pass on ahead of the people.” So they took it up and went ahead of them. And the Lord said to Joshua,
"Today I will begin to exalt you in the eyes of all Israel, so they may know that I am with you as I was with Moses. Tell the priests who carry the ark of the covenant: ‘When you reach the edge of the Jordan's waters, go and stand in the river.’”
Joshua said to the Israelites, “Come here and listen to the words of the Lord your God. This is how you will know that the living God is among you and that he will certainly drive out before you the Canaanites, Hittites, Hivites, Perizzites, Girgashites, Amorites and Jebusites. See, the ark of the covenant of the Lord of all the earth will go into the Jordan ahead of you. Now then, choose twelve men from the tribes of Israel, one from each tribe. And as soon as the priests who carry the ark of the Lord—the Lord of all the earth—set foot in the Jordan, its waters flowing downstream will be cut off and stand up in a heap.” (Joshua 3:9-13)
Now 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, the 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. The 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. (Joshua 3:15-17)
When the whole nation had finished crossing the Jordan, the Lord said to Joshua, “Choose twelve men from among the people, one from each tribe, and 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.” (Joshua 4:1-3)
“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, to serve as a sign among you. In the future, when your children ask you, ‘What do these stones mean?’ 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. (Joshua 4:5-7)
