Wyjścia 10:3 Komentarz: Rashi, Chizkuni, Ramban & Rashbam

לענת Translate as the Targum: TO BE HUMBLED. It is of the same derivation as עני poor, so that the passage signifies, “thou refusest to be poor and lowly before Me”.

ויבא משה ואהרן, Moses and Aaron arrived (at the Palace); the reason why the Torah did not mention during the other plagues that both Moses and Aaron arrived at the Palace together, is that Aaron had been present at every interview Moses had with Pharaoh. The reason that it needed to be stressed here, is that shortly the Torah will tell us that after Pharaoh had thrown out Moses and Aaron they were both recalled at Pharaoh’s servants urging him to do so. (Verse 8)

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].”
