Oracle of Isaiah: I make wise men retreat and turn their knowledge into foolishness. Isaiah 44:25

The Second Book of Isaiah describes a very special moment in the history of the chosen people: the seemingly invincible Babylonian empire fell to the Persian king Cyrus, also called "the Great," and thus the return of the exiled Jews to Jerusalem took place under the rule of this "king of kings."
The prophet Isaiah announced in the oracles of his second book that the time had been fulfilled with the forgiveness of the Lord, and a new time was to begin, a time that lasted until the conquest of Alexander the Great and the end of the Achaemenid dynasty.
And to emphasize the importance of divine providence, the prophet announced in an oracle: "I cause the signs of false prophets to fail and make fools of fortunetellers. I make wise men retreat and turn their knowledge into foolishness" Isaiah 44:25.
The exiles in Babylon had long been in contact with a country with a highly developed culture, and this oracle was a reminder that only the security or the trust in the God of Moses and Abraham could ensure the success of the return to Jerusalem and its reconstruction.
And this oracle is especially a reminder of past mistakes. Like when King Ahab wanted to take Ramon Gilead, which was in the hands of the King of Aram, and he called four hundred prophets to advise him whether to go to war or not, and God deceived the prophets so that Ahab would meet his end. According to Isaiah, God's power is sovereign, and he decides the destiny of man because he has a plan, and he enlightens or confounds the diviners and the prophets according to his eternal providence.
But the oracle also says something else: the science of the wise, wisdom, had achieved great prestige in the time of the Babylonian and Persian empires, and many wise men were chosen as advisors to the kings. The wisdom of men was in ancient times synonymous with great fame and respect, but Isaiah reminds us that not even this great science is an obstacle for God, as the Book of Job teaches; Job's wise friends tried to discover the reason for Job's suffering, and their intellectual efforts proved useless in the face of divine providence. With this, Isaiah explained that God, in his almighty providence and wisdom, inaccessible to men, determined not only the destiny of Israel but also that of all humanity.
