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.

the flowing water stood still. It backed up as far upstream as Adam, a city in the area of Zarethan, while the water flowing toward the Sea of the Arabah (the Salt Sea) was completely cut off. So the people crossed over opposite Jericho.
