﴿ فَبَدَّلَ ٱلَّذِينَ ظَلَمُوا۟ قَوْلًا غَيْرَ ٱلَّذِى قِيلَ لَهُمْ فَأَنزَلْنَا عَلَى ٱلَّذِينَ ظَلَمُوا۟ رِجْزًۭا مِّنَ ٱلسَّمَآءِ بِمَا كَانُوا۟ يَفْسُقُونَ ﴾

“But those who were bent on evildoing substituted another saying for that which had been given them: and so We sent down upon those evildoers a plague from heaven in requital for all their iniquity.”

God bestowed special blessings upon the Israelites. They should have shown their gratitude by remaining obedient to Him, but they did quite the opposite. They were given possession of a great city and told to enter it—not in a vainglorious manner—but in humility and repentance; but instead they started rejoicing in their victory.
