﴿ فَلَمَّا جَآءَهُم بِٱلْحَقِّ مِنْ عِندِنَا قَالُوا۟ ٱقْتُلُوٓا۟ أَبْنَآءَ ٱلَّذِينَ ءَامَنُوا۟ مَعَهُۥ وَٱسْتَحْيُوا۟ نِسَآءَهُمْ ۚ وَمَا كَيْدُ ٱلْكَٰفِرِينَ إِلَّا فِى ضَلَٰلٍۢ ﴾

“Now [as for Pharaoh and his followers,] when he came to them, setting forth the truth from Us, they said, “Slay the sons of those who share his beliefs, and spare [only] their women!” - but the guile of those deniers of the truth could not lead to aught but failure.”

(And when he) i.e. Moses (brought them the Truth) the Scripture (from Our presence, they said: Slay the sons of those who believe with him) i.e. return to killing the sons of those who believe in him, (and spare their women) for use as servants. (But the plot of disbelievers) the plot of Pharaoh and his folk (is in naught but error.
