Ali 'Imran 3:187

وَإِذْ أَخَذَ ٱللَّهُ مِيثَـٰقَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَـٰبَ لَتُبَيِّنُنَّهُۥ لِلنَّاسِ وَلَا تَكْتُمُونَهُۥ فَنَبَذُوهُ وَرَآءَ ظُهُورِهِمْ وَٱشْتَرَوْا۟ بِهِۦ ثَمَنًا قَلِيلًا ۖ فَبِئْسَ مَا يَشْتَرُونَ

Wa-idh akhadha l-lahu mīthāqa alladhīna ūtū l-kitāba latubayyinunnahu lilnnāsi walā taktumūnahu fanabadhūhu warāa ẓuhūrihim wa-ish'taraw bihi thamanan qalīlan fabi'sa mā yashtarūna

And [mention, O Muḥammad], when Allāh took a covenant from those who were given the Scripture, [saying], "You must make it clear [i.e., explain it] to the people and not conceal it." But they threw it away behind their backs and exchanged it for a small price. And wretched is that which they purchased.
