لَقَدْ أَخَذْنَا مِيثَٰقَ بَنِىٓ إِسْرَٰٓءِيلَ وَأَرْسَلْنَآ إِلَيْهِمْ رُسُلًۭا ۖ كُلَّمَا جَآءَهُمْ رَسُولٌۢ بِمَا لَا تَهْوَىٰٓ أَنفُسُهُمْ فَرِيقًۭا كَذَّبُوا۟ وَفَرِيقًۭا يَقْتُلُونَ
We made a covenant of old with the Children of Israel and We sent unto them messengers. As often as a messenger came unto them with that which their souls desired not (they became rebellious). Some (of them) they denied and some they slew.
Surah Al-Maaida(5:70)
