They are not different from those to whom We sent Mussa (Moses). We gave Mussa the Book -AL-Tawrah (The Torah)- and We supported him with his brother Harun (Aaron) whom We appointed a minister to be helpful and conducive to his brother to accomplish his mission

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(25:35) We gave Moses the Book *48 and appointed his brother Aaron as his counsellor:

And We had certainly given Moses the Scripture and appointed with him meaning

*48) Here by "the Book" is not meant the Torah, which was given to Prophet Moses after the exodus from Egypt, but it implies that Divine Guidance which was given to him after his appointment as a Prophet up to the Exodus. It included the orations delivered by him in the court of Pharaoh and also the instructions given to him during his conflict with Pharaoh as mentioned in the Qur'an here and there. Most probably, these things were not included in the Torah; the Torah began with the Ten Commandments which were given to Moses engraved on stone tablets on Mount Sinai after the Exodus.
