I will put hooks in thy jaws - Amasis, one of this king's generals, being proclaimed king by an insurrection of the people, dethroned Apries, and seized upon the kingdom; and Apries was obliged to flee to Upper Egypt for safety.
I will cause the fish - to stick unto thy scales - Most fish are sorely troubled with a species of insect which bury their heads in their flesh, under their scales, and suck out the vital juices. The allusion seems to be to this. Pharaoh was the crocodile; the fish, the common people; and the sticking to his scales, the insurrection by which he was wasted and despoiled of his kingdom.
Hooks in thy jaws - Compare Job 41:2. The crocodile is thus rendered an easy prey.
Fish of thy rivers - i. e., the allies of Egypt shall be involved in her ruin.
