۞ وواعدنا موسى ثلاثين ليلة واتممناها بعشر فتم ميقات ربه اربعين ليلة وقال موسى لاخيه هارون اخلفني في قومي واصلح ولا تتبع سبيل المفسدين ١٤٢
۞ وَوَٰعَدْنَا مُوسَىٰ ثَلَـٰثِينَ لَيْلَةًۭ وَأَتْمَمْنَـٰهَا بِعَشْرٍۢ فَتَمَّ مِيقَـٰتُ رَبِّهِۦٓ أَرْبَعِينَ لَيْلَةًۭ ۚ وَقَالَ مُوسَىٰ لِأَخِيهِ هَـٰرُونَ ٱخْلُفْنِى فِى قَوْمِى وَأَصْلِحْ وَلَا تَتَّبِعْ سَبِيلَ ٱلْمُفْسِدِينَ ١٤٢

The two readings either have the same meaning, or the first includes an element of mutuality: God committed to give Moses (pbuh) revelation and prophethood, and Moses committed to arrive at the Mount at the appointed time and fulfil the responsibility given to him. In the other meaning (and the second reading), it means that God “promised” in the sense of “commanded” because the command contained honour and status for Moses [Ibn ‘Ashur].
