2:174
إِنَّ ٱلَّذِينَ يَكْتُمُونَ مَآ أَنزَلَ ٱللَّهُ مِنَ ٱلْكِتَٰبِ وَيَشْتَرُونَ بِهِۦ ثَمَنًۭا قَلِيلًا ۙ أُو۟لَٰٓئِكَ مَا يَأْكُلُونَ فِى بُطُونِهِمْ إِلَّا ٱلنَّارَ وَلَا يُكَلِّمُهُمُ ٱللَّهُ يَوْمَ ٱلْقِيَٰمَةِ وَلَا يُزَكِّيهِمْ وَلَهُمْ عَذَابٌ أَلِيمٌ
Indeed, they who conceal what Allah has sent down of the Book and exchange it for a small price - those consume not into their bellies except the Fire. And Allah will not speak to them on the Day of Resurrection, nor will He purify them. And they will have a painful punishment.

Ibn Kathīr (abridged)
Criticizing the Jews for concealing what Allah revealed
Allah said:
إِنَّ الَّذِينَ يَكْتُمُونَ مَآ أَنزَلَ اللَّهُ مِنَ الْكِتَـبِ
(Verily, those who conceal what Allah has sent down of the Book.) Meaning the Jews who concealed their Book's descriptions of Muhammad ﷺ, all of which testify to his truth as a Messenger and a Prophet. They concealed this information so that they would not lose authority and the position that they had with the Arabs, where they would bring them gifts, and honor them. The cursed Jews feared that if they announced what they know about Muhammad ﷺ, then the people would abandon them and follow him. So they hid the truth so that they may retain the little that they were getting, and they sold their souls for this little profit. They preferred the little that they gained over guidance and following the truth, believing in the Messenger and having faith in what Allah was sent him with. Therefore, they have profited failure and loss in this life and the Hereafter.
As for this world, Allah made the truth about His Messenger known anyway, by the clear signs and the unequivocal proofs. Thereafter, those whom the Jews feared would follow the Prophet , believed in him and followed him anyway, and so they became his supporters against them. Thus, the Jews earned anger on top of the wrath that they already had earned before, and Allah criticized them again many times in His Book. For instance, Allah said in this Ayah (2:174 above):
إِنَّ الَّذِينَ يَكْتُمُونَ مَآ أَنزَلَ اللَّهُ مِنَ الْكِتَـبِ وَيَشْتَرُونَ بِهِ ثَمَنًا قَلِيًلا
