Thou hast broken Rahab in pieces, as one that is slain,.... Or Egypt, as in Ps 87:4 or the Egyptians, and particularly Pharaoh their king; so the Targum explains it,"Rahab or the proud one, this is Pharaoh the wicked;''who and his people were broken to pieces by the plagues that were brought upon them, especially when all their firstborn were slain; and he and his host were broke in pieces at the Red sea, and were seen by the Israelites on the shore, all dead men; and this was done as easily by the Lord, as one slain with the sword, as a dead carcass which has no life, power, and strength to defend itself, may be trampled upon, crushed, bruised, and broken to pieces, by a living man.
All this may be an emblem of the Lord's breaking in pieces the proud and insolent one Satan, as Rahab signifies; of his breaking his head, destroying his works, and spoiling his principalities and powers; and indeed of his destruction of every proud and haughty sinner, that says, Pharaoh like, who is the Lord, that I should obey him?
