Aal-'Imran - 3:187

وَإِذَ أَخَذَ اللّهُ مِيثَاقَ الَّذِينَ أُوتُواْ الْكِتَابَ لَتُبَيِّنُنَّهُ لِلنَّاسِ وَلاَ تَكْتُمُونَهُ فَنَبَذُوهُ وَرَاء ظُهُورِهِمْ وَاشْتَرَوْاْ بِهِ ثَمَناً قَلِيلاً فَبِئْسَ مَا يَشْتَرُونَ
[3:187]
And when Allah made a covenant with those who were given the Book: You shall certainly make it known to men and you shall not hide it; but they cast it behind their backs and took a small price for it; so evil is that which they buy.
And remember Allah took a covenant from the People of the Book, to make it known and clear to mankind, and not to hide it; but they threw it away behind their backs, and purchased with it some miserable gain! And vile was the bargain they made!
And (remember) when Allah laid a charge on those who had received the Scripture (He said): Ye are to expound it to mankind and not to hide it. But they flung it behind their backs and bought thereby a little gain. Verily evil is that which they have gained thereby.
