most have forgotten what they've been told to bear in mind

فَبِمَا نَقْضِهِم مِّيثَـٰقَهُمْ لَعَنَّـٰهُمْ وَجَعَلْنَا قُلُوبَهُمْ قَـٰسِيَةً ۖ يُحَرِّفُونَ ٱلْكَلِمَ عَن مَّوَاضِعِهِۦ ۙ وَنَسُوا۟ حَظًّا مِّمَّا ذُكِّرُوا۟ بِهِۦ ۚ وَلَا تَزَالُ تَطَّلِعُ عَلَىٰ خَآئِنَةٍ مِّنْهُمْ إِلَّا قَلِيلًا مِّنْهُمْ ۖ فَٱعْفُ عَنْهُمْ وَٱصْفَحْ ۚ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُحْسِنِينَ

But they broke their pledge, so We distanced them [from Us] and hardened their hearts. They distort the meaning of [revealed] words and have forgotten some of what they were told to remember: you [Prophet] will always find treachery in all but a few of them. Overlook this and pardon them: God loves those who do good.

وَمِنَ ٱلَّذِينَ قَالُوٓا۟ إِنَّا نَصَـٰرَىٰٓ أَخَذْنَا مِيثَـٰقَهُمْ فَنَسُوا۟ حَظًّا مِّمَّا ذُكِّرُوا۟ بِهِۦ فَأَغْرَيْنَا بَيْنَهُمُ ٱلْعَدَاوَةَ وَٱلْبَغْضَآءَ إِلَىٰ يَوْمِ ٱلْقِيَـٰمَةِ ۚ وَسَوْفَ يُنَبِّئُهُمُ ٱللَّهُ بِمَا كَانُوا۟ يَصْنَعُونَ

We also took a pledge from those who say, ‘We are Christians,’ but they too forgot some of what they were told to remember, so We stirred up enmity and hatred among them until the Day of Resurrection, when God will tell them what they have done.
