قَالَ هَلْ ءَامَنُكُمْ عَلَيْهِ إِلَّا كَمَآ أَمِنتُكُمْ عَلَىٰٓ أَخِيهِ مِن قَبْلُ ۖ فَٱللَّهُ خَيْرٌ حَٰفِظًا ۖ وَهُوَ أَرْحَمُ ٱلرَّٰحِمِينَ
Commentary:
In the words, Allah is the best Protector, Jacob administers a subtle rebuke to his sons by hinting to them that, after their tragic experience with Joseph, it is a pity that even now they should not rely on the protection of God but on their own power. He further hints that he had not entrusted Joseph to their care before, nor would he now entrust his brother to their protection. His trust now, as before, lay in God alone.
