John Gill

Where are they? where are thy wise men?.... The magicians and soothsayers, the diviners and astrologers, who pretended, by their magic art and skill in judicial astrology, to foretell things to come: this is an address to the king of Egypt, who had such persons about him, and encouraged them, by consulting them on occasion, and rewarding them: and let them tell thee now, and let them know what the Lord of hosts hath purposed upon Egypt; or, "against it"; let them tell, if they can, and make known unto thee the purposes of God's heart, the things he has resolved upon, even the calamities and punishments he will shortly inflict upon the Egyptians, of which he has given notice by his prophets.
