Comentario citado sobre Sofonías 3:19

He wished to reveal the End... [How does Rashi know this? The answer is:] Since Scripture uses two expressions, “gather around” and “come together,” it hints to the End. For it is written (Yeshayah 66:12), “He will gather the scattered ones of Yehudah.” And it is written (Tzephaniah 3:19), “He will gather the lost one,” which hints to the last exile. Anoher answer: Since it is written, “In latter days,” which is superfluous, [perforce] it hints to the End of Days which will be in latter days.

פקד פקדתי אתכם, “I have surely remembered you.” The Torah speaks here of two distinct remembrances. One is that Israel is being remembered, the other that the שכינה, which had descended with Yaakov to Egypt and had been exiled and subjected to abuse together with the Jewish people, was also now being “remembered.” The שכינה had been alluded to at the time by the letter ה at the end of the word מצרימה in Genesis 46,4 where G’d had promised to also bring it up again as we have explained there. The שכינה referred to by our sages in that context is none other than the כנסת ישראל which is referred to in verse nine as צעקת בני ישראל. This is also the reason that G’d said to Moses that He had remembered אתכם ואת העשוי לכם במצרים, “you and the כנסת ישראל,” the letter ה of the word מצרימה which we referred to earlier as proof that the שכינה descended to Egypt also. It is this שכינה which shared the pain that the Jewish people were experiencing.
As to the meaning of the word עשוי, “what has been done.” The word is related to Tzefaniah 33,19 הנני עושה את כל מעניך, which means that G’d is actively suffering as a result of His people suffering from by the Gentiles.
