Exodus 14:17

To pursue. God did not restrain the perverse will of the Egyptians; but suffered them to be guided by their blind passions, and to rush presumptuously into the bed of the sea. If the retiring of its waters had been owing to any natural cause, this wise nation could not be ignorant but that, at the stated time, the ebbing would cease, and consequently that they would be overtaken by the waters. But the waters stood up like walls on both sides, and they were so infatuated as to suppose that the miracle would be continued for their protection. (Haydock)
