Egypt will hiss like a fleeing serpent, for the enemy will advance in force; with axes they will come against her like woodsmen cutting down trees.
To study elegance was not so much the object of the Prophet, as to confirm what he had taught. The figures, then, which he now uses, were not intended as ornaments of speech, but rather for the purpose of giving force and power to what he had said; for, as it has been said, prophecies had no credit with stupid men, unless stimulants were added to them.
In these verses we have, I. Confusion and terror spoken to Egypt. The accomplishment of the prediction in the former part of the chapter disabled the Egyptians from making any attempts upon other nations; for what could they do when their army was routed? But still they remained strong at home, and none of their neighbours durst make any attempts upon them.
Commenting on Jeremiah 46:13-28
The voice thereof shall go like a serpent,.... That is, the voice of Egypt, before compared to a heifer, when in its glory; but now it shall not bellow like a heifer in fat pasture, bat hiss like a serpent, when drove out of its hole, and pursued; signifying, that their voice should be low and submissive, and should not speak one big or murmuring word to their conquerors.
