(Jacob Senses Joseph)
When they went (to Joseph), they entered in accordance with their father’s instructions. Although this could not change anything decreed by God, Jacob had a private reason for asking them to do this. For he possessed certain knowledge that we taught him, but most people do not know.
وَلَمّا دَخَلوا مِن حَيثُ أَمَرَهُم أَبوهُم ما كانَ يُغنى عَنهُم مِنَ اللَّهِ مِن شَىءٍ إِلّا حاجَةً فى نَفسِ يَعقوبَ قَضىٰها وَإِنَّهُ لَذو عِلمٍ لِما عَلَّمنٰهُ وَلٰكِنَّ أَكثَرَ النّاسِ لا يَعلَمونَ
wa lammaa dakhaloo min haisu amarahum aboohum maa kaana yughnee ‘anhum minal laahi min shai’in illaa haajatan fee nafsi Ya’qooba qadaahaa; wa innahoo lazoo ‘ilmil limaa ‘allamnaahu wa laakinna aksaran naasi laa ya’lamoon
