“And ease for me my task; and untie the knot from my tongue, so that they may understand my speech. And appoint for me a minister from my family: Aaron, my brother. Strengthen me through him, and make him share in my task.”
“And ease for me my task,” that is: make easy for me what You have commanded me to do in conveying the message to Pharaoh. “And untie the knot from my tongue.” This was because, when Moses was a small child in Pharaoh’s care, he once struck Pharaoh and seized his beard. Pharaoh said to his wife Asiya, “This is my enemy,” and intended to kill him. But Asiya said, “He is only a child; he has neither understanding nor discernment.”
Another report relates that, when Moses’s mother had weaned him, she returned him, and Moses grew up in the care of Pharaoh and his wife Asiya, who raised him and adopted him as a son. One day, while he was playing before Pharaoh and holding a sceptre with which he was playing, he raised it and struck Pharaoh on the head. Pharaoh became enraged and took the blow as an evil omen, to the point that he intended to kill him. Asiya said, “O King, he is a small child without understanding; test him, if you wish.” She then brought two basins: one containing live coals and the other jewels, and placed them before Moses. He wished to take the jewels, but Gabriel took Moses’s hand and placed it upon the fire. He took a live coal and put it in his mouth, burning his tongue and leaving him with an impediment. (1)
“So that they may understand my speech.” That is, untie the knot so that they may understand what I say. “And appoint for me a minister”—a helper and supporter—“from my family.” A minister is one who assists and supports you, bearing some of the burden of your work. He then clarified who he meant: “Aaron, my brother.” Aaron was four years older than Moses. He was more eloquent in speech, more handsome and more comely, and fairer in complexion. Moses was dark-complexioned, aquiline-nosed, and curly-haired.
“Strengthen me through him,” that is, strengthen my back through him. “And make him share in my task,” meaning, in prophethood and in conveying the message. Ibn Amir recited “I will strengthen” with the initial alif pronounced with a fatḥah, and “I will make him share” with it pronounced with a ḍammah, as a response, reporting Moses’s words; that is, “I will do that.” The remaining reciters read both as a supplication.
