﴿ لَوْلَا يَنْهَىٰهُمُ ٱلرَّبَّٰنِيُّونَ وَٱلْأَحْبَارُ عَن قَوْلِهِمُ ٱلْإِثْمَ وَأَكْلِهِمُ ٱلسُّحْتَ ۚ لَبِئْسَ مَا كَانُوا۟ يَصْنَعُونَ ﴾

“Why do not their men of God and their rabbis forbid them to make sinful assertions and to swallow all that is evil? Vile indeed is what they contrive!”

Why do the rabbis and the priests among them not forbid them from uttering sin calumny and consuming unlawful gain? Evil is what they have been doing in refraining from forbidding them.
