13وَيَضيقُ صَدري وَلا يَنطَلِقُ لِساني فَأَرسِل إِلىٰ هارونَMuhammad Asadand then my breast will be straitened and my tongue will not be free: send, then, [this Thy command] to Aaron.1Cf. 20:25-34 and the corresponding notes. In the present context, stress is laid on the deep humility of Moses, who considered himself incapable of fulfilling the task for which he had been chosen, and asked God to entrust it to Aaron instead.
