The great dragon. — This word is usually translated dragon in the English version, but sometimes whale (Ezekiel 32:2), and (in a slightly modified form) serpent (Exodus 7:9-10; Exodus 7:12). It unquestionably means crocodile, the characteristic animal of Egypt, in some parts hated and destroyed, in some worshipped as a deity, but in all alike feared, and regarded as the most powerful and destructive creature of their country.
Lieth in the midst of his rivers. — Egypt, a creation of the Nile, and dependent entirely upon it for its productiveness, is personified by the crocodile, its characteristic animal, basking upon the sand-banks of its waters. The expression “his rivers,” used of the branches of the Nile near its mouth, is peculiarly appropriate to the Twenty-sixth Dynasty, to which Pharaoh-Hophra belonged, whose capital was Sais, in the midst of the Delta.
My river is mine own. — This is characteristic of the pride of Hophra, who, according to Herodotus, was accustomed to say that “not even a god could dispossess him of power.” The whole dynasty to which he belonged, beginning with Psammeticus, improved the river and encouraged commerce with foreign nations, thereby acquiring great wealth.
