﴿ إِلَىٰ فِرْعَوْنَ وَمَلَإِي۟هِۦ فَٱسْتَكْبَرُوا۟ وَكَانُوا۟ قَوْمًا عَالِينَ ﴾

“unto Pharaoh and his great ones; but these behaved with arrogance, for they were people wont to glorify [only] themselves.”

(Unto Pharaoh and his chiefs, but they scorned (them)) they were too proud to believe in Moses and the signs (and they were despotic folk) they opposed Moses and felt too proud to believe.
