Allah tells us that He made a declaration to the Children of Israel in the Scripture, meaning that He had already told them in the Book which He revealed to them, that they would cause mischief on the earth twice, and would become tyrants and extremely arrogant, meaning they would become shameless oppressors of people, Allah says:

[وَقَضَيْنَآ إِلَيْهِ ذَلِكَ الاٌّمْرَ أَنَّ دَابِرَ هَـؤُلآْءِ مَقْطُوعٌ مُّصْبِحِينَ ]

(And We made known this decree to him, that the root of those (sinners) was to be cut off in the early morning.)(15:66), meaning, We already told him about that and informed him of it.
