Sforno
ישלח אתכם מזה כשלחו, in the same manner as he has already expelled both you and Aaron from his presence when he had lost his cool. (compare 10,11). When he will send the whole people of Israel from his land, he will act under a similar type of stress.
Kli Yakar
“When he sends you away, he will drive you out completely from here.” Rashi explained “he will send all of you.” It seems that the word when he sends you is superfluous. I say that this is the explanation: Moses was distressed because he was humiliated when Pharaoh drove him away twice. In the plague of locusts it is written and he drove them away from before Pharaoh, and in the plague of darkness, Pharaoh said to him, ‘Go away from me.’ The Holy One, blessed be He, responded to him, “Do not be distressed, for this is a bad sign for Pharaoh, as he began to drive you out little by little, until in the end he will drive out all of you.” For at first it says, and he drove them away from before Pharaoh, but it did not say that they should not see his face again. Later, he increased the expulsion by saying, Do not see my face again. But in the end, when he sends you, when the time comes that he will send you, then he will drive all of you out, not like the first time when the expulsion was lighter, for he only drove out Moses and Aaron. But when he sends you, then he will drive you out completely. This is precisely deduced from the word when he sends you.
Ramban
AND MOSES AND AARON CAME IN UNTO PHARAOH. Rabbi Abraham ibn Ezra commented: “We know that Moses never came to Pharaoh without being accompanied by Aaron, who was the interpreter.11Above, 7:2. Scripture here makes a point of mentioning Moses and Aaron in order [to make clear] that Pharaoh’s command that both of them be brought again before him12Further, Verse 8. and his final act of driving them out13Ibid., Verse 11. — something he had not done previously — [applied to the two brothers alike].”
