Read Joshua 3:16 Using Other Translations
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 waters coming down from above stood and rose up in a heap very far away, at Adam, the city that is beside Zarethan, and those flowing down toward the Sea of the Arabah, the Salt Sea, were completely cut off. And the people passed over opposite Jericho.
the water above that point began backing up a great distance away at a town called Adam, which is near Zarethan. And the water below that point flowed on to the Dead Sea until the riverbed was dry. Then all the people crossed over near the town of Jericho.
