ציטירנדיקער פּירוש אויף שמות 3:21

While still standing before Pharaoh. . . You might ask: Earlier (11:1), it says similarly: “Hashem said to Moshe, ‘There is one more plague. . .’” Furthermore, “I will not see your face again” was written previous to it. Why then did Rashi not make a similar comment there? The answer is: The content of the earlier verse (11:1) was actually told to Moshe before, for it is written (3:21): “I will give this people grace. . .” But it is merely repeated here, because now was the time for its fulfillment. This section, in contrast, is dealing with the exodus from Egypt, and that the plague will be at midnight, was not hinted anywhere else. Perforce, this prophecy was told to Moshe while still standing before Pharaoh. You might ask: If Moshe would not even offer a simple prayer within the city, how could he be given a full prophecy there [see Rashi 11:1]? The answer is: [Hashem did it] for Moshe’s honor so that he should not be considered a liar. Otherwise, Moshe would need to go back to Pharaoh [to announce Hashem’s prophecy, but Moshe had already told Pharaoh that he would not see his face again]. Alternatively: Hashem lifted Moshe ten handbreadths above the ground when He spoke to him, thus placing him in a separate domain. (Re”m)

ושאלה אשה משכנתה, as an outright gift. After all, G’d had encouraged the people to ask for these gifts, the Torah telling us in verse 21 that G’d would make the people favourably disposed towards the Israelites so that they would not refuse such requests. The expression שאל in the same sense as here occurs also in Psalms 2,8 שאל ממני ואתנה גוים נחלתך, “Ask it of me, and I will make the nations your domain.” This is the principal meaning of the verse and it effectively silences the heretics who speak of the Jews borrowing and not giving back these trinkets.

וה' נתן את חן העם, “and the Lord had disposed the Egyptians favourably towards this people;” this is how He fulfilled what He had said to Moses in Exodus 3,21, when He told him that the Israelites would not leave Egypt emptyhanded.
