Joshua 4:18-24

Then the priests carried the Ark of the Agreement with the LORD out of the river. As soon as their feet touched dry land, the water began flowing again. The river again overflowed its banks, just as it had before they crossed. The people crossed the Jordan on the tenth day of the first month and camped at Gilgal, east of Jericho. They carried with them the twelve rocks taken from the Jordan, and Joshua set them up at Gilgal. Then he spoke to the Israelites: “In the future your children will ask you, ‘What do these rocks mean?’ Tell them, ‘Israel crossed the Jordan River on dry land. The LORD your God caused the water to stop flowing until you finished crossing it, just as the LORD did to the Red Sea. He stopped the water until we crossed it. The LORD did this so all people would know he has great power and so you would always respect the LORD your God.’ ”
