Why didn't Yusuf (as) reveal his identity to his brothers, when they first came to him?
وَجَاءَ إِخْوَةُ يُوسُفَ فَدَخَلُوا عَلَيْهِ فَعَرَفَهُمْ وَهُمْ لَهُ مُنكِرُونَ - 12:58
And the brothers of Joseph came [seeking food], and they entered upon him; and he recognized them, but he was to them unknown.
From what I understand, he was going to forgive his brothers and wanted to essentially bring his brothers & parents to Egypt, and this perhaps could have been achieved by just revealing his identity at the first instance?
As opposed to requesting that they bring Benjamin, then hiding a cup in his luggage etc.?
Not questioning what happened or whether this was the best course of action. Just interested to hear what scholars of tafsir/quran have said about this.
