Yet he also is wise. Intense irony. "Wisdom is not wholly confined to the human counselors whose advice Judah follows (Isaiah 29:14). He (Jehovah) is 'wise' too, and could give prudent counsel if his advice were asked."
As he is not consulted, he will bring evil upon his people, and will not call back, or retract, his words of threatening, but will give them accomplishment, by rising up against the house of the evil-doers (i.
e. the Jews), and their help (i.e. the Egyptians).
