We now, then, see why the Prophet puts these questions: and a question has much more force when it refers to what is in no way doubtful. What! can God be angry with rivers? Who can imagine God to be so unreasonable as to disturb the sea and to change the nature of things, when a certain order has been established by his own command? Why should he dry the sea, except he had something in view, even the deliverance of his Church? except he intended to save his people from extreme danger, by stretching forth his hand to the Israelites, when they thought themselves utterly lost? He therefore denies, that when God dried the Red Sea, and when he stopped the flowing of Jordan, he had put forth his power against the sea or against the river, as though he was angry with them. The design of God, says the Prophet, was quite another; for God rode on his horses, that is, he intended to show that all the elements were under his command, and that for the salvation of his people. That God, then, might be the redeemer of his Church, he constrained Jordan to turn back its course, he constrained the Red Sea to make a passage for his miserable captives, who would have otherwise been exposed to the slaughter of their enemies. There was indeed no hope of saving Israel, without a passage being suddenly opened to them through the Red Sea.
