Pharaoh's stubbornness

وَلَمَّا وَقَعَ عَلَيْهِمُ ٱلرِّجْزُ قَالُوا۟ يَـٰمُوسَى ٱدْعُ لَنَا رَبَّكَ بِمَا عَهِدَ عِندَكَ ۖ لَئِن كَشَفْتَ عَنَّا ٱلرِّجْزَ لَنُؤْمِنَنَّ لَكَ وَلَنُرْسِلَنَّ مَعَكَ بَنِىٓ إِسْرَٰٓءِيلَ

And when the punishment descended upon them, they said, "O Moses, invoke for us your Lord by what He has promised you. If you [can] remove the punishment from us, we will surely believe you, and we will send with you the Children of Israel."

وَلَقَدْ أَرَيْنَـٰهُ ءَايَـٰتِنَا كُلَّهَا فَكَذَّبَ وَأَبَىٰ

And We certainly showed him [i.e., Pharaoh] Our signs - all of them - but he denied and refused.

قَالَ فِرْعَوْنُ وَمَا رَبُّ ٱلْعَـٰلَمِينَ

Said Pharaoh, "And what is the Lord of the worlds?"

قَالَ لِمَنْ حَوْلَهُۥٓ أَلَا تَسْتَمِعُونَ

[Pharaoh] said to those around him, "Do you not hear?"
