A helper from my family
At the burning bush Musa asked for a minister from his family, his brother Harun, to strengthen him and share his task. Elsewhere he said Harun was more eloquent than he, and asked that he be sent as a supporter to confirm him. Allah granted the request, gave Harun prophethood, and sent them both with His signs.
وَٱجْعَل لِّى وَزِيرًۭا مِّنْ أَهْلِى ﴿29﴾ هَٰرُونَ أَخِى ﴿30﴾ ٱشْدُدْ بِهِۦٓ أَزْرِى ﴿31﴾ وَأَشْرِكْهُ فِىٓ أَمْرِى ﴿32﴾ كَىْ نُسَبِّحَكَ كَثِيرًۭا ﴿33﴾ وَنَذْكُرَكَ كَثِيرًا ﴿34﴾ إِنَّكَ كُنتَ بِنَا بَصِيرًۭا ﴿35﴾ قَالَ قَدْ أُوتِيتَ سُؤْلَكَ يَٰمُوسَىٰ ﴿36﴾
(29) And appoint for me a minister from my family - (30) Aaron, my brother. (31) Increase through him my strength (32) And let him share my task (33) That we may exalt You much (34) And remember You much. (35) Indeed, You are of us ever Seeing." (36) [Allah] said, "You have been granted your request, O Moses.
وَأَخِى هَٰرُونُ هُوَ أَفْصَحُ مِنِّى لِسَانًۭا فَأَرْسِلْهُ مَعِىَ رِدْءًۭا يُصَدِّقُنِىٓ ۖ إِنِّىٓ أَخَافُ أَن يُكَذِّبُونِ ﴿34﴾ قَالَ سَنَشُدُّ عَضُدَكَ بِأَخِيكَ وَنَجْعَلُ لَكُمَا سُلْطَٰنًۭا فَلَا يَصِلُونَ إِلَيْكُمَا ۚ بِـَٔايَٰتِنَآ أَنتُمَا وَمَنِ ٱتَّبَعَكُمَا ٱلْغَٰلِبُونَ ﴿35﴾
(34) And my brother Aaron is more fluent than me in tongue, so send him with me as support, verifying me. Indeed, I fear that they will deny me." (35) [Allah] said, "We will strengthen your arm through your brother and grant you both supremacy so they will not reach you. [It will be] through Our signs; you and those who follow you will be the predominant."
وَوَهَبْنَا لَهُۥ مِن رَّحْمَتِنَآ أَخَاهُ هَٰرُونَ نَبِيًّۭا
And We gave him out of Our mercy his brother Aaron as a prophet.
