יונה, פרק ג׳, פסוק י׳

The repentance of the people of Nineveh reaches its climax, lifting the heavy decree that hovered over the city. The focus shifts entirely from outward displays of mourning and fasting to a profound, practical transformation of character, which ultimately leads to divine forgiveness.

When God looked upon the city, He did not examine their fasting or external habits of grief. Instead, He focused on their actual deeds. The people of Nineveh did not settle for mere feelings of regret in their hearts. They carried out the king's orders in practice and actively corrected their behavior [מצודת דוד, מלבי״ם, ביאור שטיינזלץ]. Another perspective suggests that the divine gaze focused on the fact that the people now truly believed in Him [אבן עזרא].

Turning away from an evil path involved abandoning all sins, but the primary focus was on correcting the crimes of robbery and violence. Their repentance was so thorough and practical that they returned stolen property to its rightful owners, even if it required tearing down an entire building just to extract and return a single stolen wooden beam [רד״ק]. Since the original decree of destruction was sealed specifically because of the sin of robbery, addressing this social injustice was sufficient. Even though the people of Nineveh did not abandon their idolatry, the practical correction of their crimes against one another was enough to cancel the punishment intended for them [מלבי״ם].

Following this practical change, God reconsidered the decree and decided to withhold the disaster He had planned to bring upon them [רש״י, מצודת דוד]. The description of God changing His mind is simply an instance of the Torah speaking in human terms [אבן עזרא]. This cancellation of the decree does not indicate a random shift in divine will. Rather, it reveals a fundamental principle in how God governs the world. All prophecies of doom and threats of punishment are issued conditionally. God does not desire to bring disaster upon humanity, but rather to awaken people to change their ways. The moment a person turns away from a wicked path, divine forgiveness is activated, and the punishment is annulled [רד״ק, ביאור שטיינזלץ].
