Paulus Orosius

The Hebrews proceeded safely over the dry passage, and the masses of stationary water collapsed behind them. The entire Egyptian multitude with their king was overwhelmed and killed, and the entire province, which had previously been tortured by plagues, became empty by this last slaughter. Even today there exists most reliable evidence of these events. For the tracks of chariots and the ruts made by the wheels are visible not only on the shore but also in the deep, as far as sight can reach. And if perchance for the moment they are disturbed either accidentally or purposely, they are immediately restored through divine providence by winds and waves to their original appearances, so that whoever is not taught to fear God by the study of revealed religion may be terrified by his anger through this example of his accomplished vengeance.
