arrogance and false confidence

فَأَجْمِعُوا۟ كَيْدَكُمْ ثُمَّ ٱئْتُوا۟ صَفًّا ۚ وَقَدْ أَفْلَحَ ٱلْيَوْمَ مَنِ ٱسْتَعْلَىٰ

So resolve upon your plan and then come [forward] in line. And he has succeeded today who overcomes."

قَالُوا۟ يَـٰمُوسَىٰٓ إِمَّآ أَن تُلْقِىَ وَإِمَّآ أَن نَّكُونَ أَوَّلَ مَنْ أَلْقَىٰ

They said, "O Moses, either you throw or we will be the first to throw."

فَلَمَّا جَآءَ ٱلسَّحَرَةُ قَالُوا۟ لِفِرْعَوْنَ أَئِنَّ لَنَا لَأَجْرًا إِن كُنَّا نَحْنُ ٱلْغَـٰلِبِينَ

And when the magicians arrived, they said to Pharaoh, "Is there indeed for us a reward if we are the predominant?"

فَأَلْقَوْا۟ حِبَالَهُمْ وَعِصِيَّهُمْ وَقَالُوا۟ بِعِزَّةِ فِرْعَوْنَ إِنَّا لَنَحْنُ ٱلْغَـٰلِبُونَ

So they threw their ropes and their staffs and said, "By the might of Pharaoh, indeed it is we who are predominant."
