Gregory of Nyssa
Joshua halted the current of the Jordan River, but this cessation only persisted while the ark of the covenant was immersed in the waters. Once the people had traversed and the ark was lifted from the river, the waters returned to their usual course. In the case of the Red Sea, its depths lay bare as the wind divided the waters; however, this miraculous event continued only until the army had crossed over on dry ground. Subsequently, the waters reunited, and what had been separated for a brief moment became whole once more. The significance of this occurrence remains unaltered by the passage of time, continually affirmed by the evidence of its lasting impact.
