The Reed Sea did not overflow its banks, but stood up in a heap on each side of the way through the sea. The heaps had to be high because this path was miles wide; enough for two or three million people and their animals to cross in just a few hours. They could not have run, but had to have a considerable amount of time and an area quite a few miles wide to make the crossing. It is impossible for water to stand in a heap – or in two heaps.
