וַיֹּ֥אמֶר מֹשֶׁ֖ה כֵּ֣ן דִּבַּ֑רְתָּ לֹא־אֹסִ֥ף ע֖וֹד רְא֥וֹת פָּנֶֽיךָ׃ (פ)
И сказал Моисей: 'Ты хорошо говорил; Я больше не увижу твоего лица.'
Rashi
כן דברת signifies RIGHTLY HAST THOU SPOKEN, and in its proper time hast thou spoken; for it is true that I will not see thy face again (Mekhilta; Exodus Rabbah 18:1; cf. also Onkelos).
Ramban
AND MOSES SAID: THOU HAST SPOKEN WELL; I WILL NOT SEE THY FACE AGAIN ANY MORE. That is, “I will not see you again after I leave you.” After the plague of the firstborn, Moses did not see Pharaoh. The meaning of the verse, And he called for Moses and Aaron,70Further, 12:31. is [not that he called them to come to see him, but instead] that he himself went to the entrance of their home and shouted in the darkness, Rise up, get you forth from among my people.70Further, 12:31. Perhaps he sent the message to them by Egyptians, of whom it is said, And the Egyptians were urgent upon the people to send them out of the land in haste.71Ibid., Verse 33.
It is possible that the verse, I will not see thy face again any more, means “in your palace,” namely, “I will not come to you any more.” And so the Rabbis have said in Eileh Shemoth Rabbah:72Shemoth Rabbah 14:4. “You have spoken well in saying, See my face no more.73Verse 28. I will not come to you again; you will come to me.”74According to this Midrash then, Moses did see Pharaoh later, but the king came to him. According to the first explanation, however, after he left the palace this time, Moses no longer saw Pharaoh at all.

Rabbeinu Bahya
לא אוסיף עוד ראות פניך, “I will not again see your face.” Shemot Rabbah 18,1 understands these words as “I will not again come to you but you will trouble yourself to come to see me.” This is the meaning of (11,8) “all these your servants will come down to me.” He should really have said: “you yourself will come down to me.” However, even at this stage, Moses still preserved the diplomatic niceties by phrasing what he said to Pharaoh in as inoffensive a manner as was possible. He therefore made it appear as if this “climb down” would be initiated by Pharaoh’s servants. The fact is, however, that when the Torah describes what happened (12, 30-31) it is clear that the initiative was Pharaoh’s, “Pharaoh arose during the night, he and all his servants..and he said: ‘rise and leave from the midst of my people, etc., etc.’”
