Was the Lord displeased against the rivers? [was] thine anger against the rivers?.... Referring, as is commonly thought, either to the rivers in Egypt turned into blood, which was one of the plagues of that land, Ex 7:20 when the resentment of the Lord was not so much against them as against the Egyptians; and as a punishment of them for drowning the infants of the Israelites in them, and in order to obtain the dismissal of his people from that land: or else to the river Jordan, called "rivers", because of the largeness of it, and the abundance of water in it; against which the Lord was not angry, when he divided the waters of it, which was done only to make a passage through it for his people into the land of Canaan, Jos 3:16:[was] thy wrath against the sea, that thou didst ride upon thine horses [and] thy chariots of salvation?
the Red sea, when a strong east wind was sent, and divided the waters of it, which was no mark of displeasure against that; but for the benefit of the people of Israel, that they might pass through it as on dry land; and for the destruction of Pharaoh and his hosts, who, entering into it with his horses and chariots, were drowned; the Lord coming forth against him, riding on his horses and chariots, the pillar of fire and cloud, by which he defended Israel, and through which he looked, and discomfited the host of the Egyptians, and wrought salvation for his people; seeEx 14:19 with which compare Ps 114:3.
