Charles Ellicott Commentary Isaiah 31:2

"Yet he also is wise, and will bring evil, and will not call back his words, but will arise against the house of the evil-doers, and against the help of them that work iniquity." — Isaiah 31:2 (ASV)

Yet he also is wise. — The words have a ring of sarcasm in them. Isaiah admits ironically that the counselors of Hezekiah were wise in their generation. He reminds them that there might be some little wisdom in Jehovah, and in the prophet by whom He spoke.

And will not call back his words. — Such words, e.g., as those of the preceding chapter (Isaiah 30:12–13; Isaiah 30:16–17).
