It is a common tater.

He is a commentator.

(ב) וַיֹּ֡אמֶר קַח־נָ֠א אֶת־בִּנְךָ֨ אֶת־יְחִֽידְךָ֤ אֲשֶׁר־אָהַ֙בְתָּ֙ אֶת־יִצְחָ֔ק וְלֶ֨ךְ־לְךָ֔ אֶל־אֶ֖רֶץ הַמֹּרִיָּ֑ה וְהַעֲלֵ֤הוּ שָׁם֙ לְעֹלָ֔ה עַ֚ל אַחַ֣ד הֶֽהָרִ֔ים אֲשֶׁ֖ר אֹמַ֥ר אֵלֶֽיךָ׃
(2) “Take your son, your favored one, Isaac, whom you love, and go to the land of Moriah, and offer him there as a burnt offering on one of the heights that I will point out to you.”
(ב)את בנך. אָמַר לוֹ שְׁנֵי בָנִים יֵשׁ לִי, אָמַר לוֹ אֶת יְחִידְךָ; אָמַר לוֹ זֶה יָחִיד לְאִמּוֹ וְזֶה יָחִיד לְאִמּוֹ, אָמַר לוֹ אֲשֶׁר אָהַבְתָּ; אָמַר לוֹ שְׁנֵיהֶם אֲנִי אוֹהֵב, אָמַר לוֹ אֶת יִצְחָק (סנהדרין פ"ט).
(2) את בנך THY SON — Abraham said to God, “I have two sons”. “He answered him, “Thine only son”. Abraham said, “This one is the only son of his mother and the other is the only son of his mother”. God then said, “the one whom thou lovest”. Abraham replied, “I love both of them”. Whereupon God said “even Isaac”. (Sanhedrin 89b:11)
(יב) וַיֹּ֣אמֶר יְהֹוָה֮ אֶל־מֹשֶׁה֒ אֱמֹר֙ אֶֽל־אַהֲרֹ֔ן נְטֵ֣ה אֶֽת־מַטְּךָ֔ וְהַ֖ךְ אֶת־עֲפַ֣ר הָאָ֑רֶץ וְהָיָ֥ה לְכִנִּ֖ם בְּכׇל־אֶ֥רֶץ מִצְרָֽיִם׃
(12) Then GOD said to Moses, “Say to Aaron: Hold out your rod and strike the dust of the earth, and it shall turn to lice throughout the land of Egypt.”
(א)אמר אל אהרן. לֹא הָיָה הֶעָפָר כְּדַאי לִלְקוֹת עַ"יְ מֹשֶׁה, לְפִי שֶׁהֵגֵן עָלָיו כְּשֶׁהָרַג אֶת הַמִּצְרִי וַיִּטְמְנֵהוּ בַּחוֹל, וְלָקָה עַל יְדֵי אַהֲרֹן (שמות רבה):
(1) אמר אל אהרן SAY UNTO AARON — The dust did not deserve to be smitten by Moses because it had protected him when he slew the Egyptian, for “he hid him in the sand”; and it was therefore smitten by Aaron (Tanchuma; Exodus Rabbah 10:7).
(י) וַיֹּ֖אמֶר מֶ֣ה עָשִׂ֑יתָ ק֚וֹל דְּמֵ֣י אָחִ֔יךָ צֹעֲקִ֥ים אֵלַ֖י מִן־הָֽאֲדָמָֽה׃
(10) “What have you done? Hark, your brother’s blood [literally "bloods"] cries out to Me from the ground!
(א)דמי אחיך. דָּמוֹ וְדַם זַרְעִיּוֹתָיו.
(1) דמי אחיך THY BROTHERS BLOOD — דמי is plural — bloods” — his blood and the blood of his possible descendants (Genesis Rabbah 22:9).
(ה) וַיֵּ֣רֶד יְהֹוָ֔ה לִרְאֹ֥ת אֶת־הָעִ֖יר וְאֶת־הַמִּגְדָּ֑ל אֲשֶׁ֥ר בָּנ֖וּ בְּנֵ֥י הָאָדָֽם׃
(5) GOD came down to look at the city and tower that the mortals had built,
(א)וירד ה' לראות. לֹא הֻצְרַךְ לְכָךְ, אֶלָּא בָא לְלַמֵּד לְדַיָּנִים שֶׁלֹּא יַרְשִׁיעוּ הַנִּדּוֹן עַד שֶׁיִּרְאוּ וְיָבִינוּ, מִדְרַשׁ רַבִּי תַנְחוּמָא:
(1) 'וירד ה לראות AND THE LORD CAME DOWN TO SEE — God really did not need to do this, but Scripture intends to teach the judges that they should not proclaim a defendant guilty before they have seen the case and thoroughly understand the matter in question. This is to be found in Midrash of R. Tanchuma.
(ו) וַתֵּ֣רֶא הָֽאִשָּׁ֡ה כִּ֣י טוֹב֩ הָעֵ֨ץ לְמַאֲכָ֜ל וְכִ֧י תַֽאֲוָה־ה֣וּא לָעֵינַ֗יִם וְנֶחְמָ֤ד הָעֵץ֙ לְהַשְׂכִּ֔יל וַתִּקַּ֥ח מִפִּרְי֖וֹ וַתֹּאכַ֑ל וַתִּתֵּ֧ן גַּם־לְאִישָׁ֛הּ עִמָּ֖הּ וַיֹּאכַֽל׃
(6) When the woman saw that the tree was good for eating and a delight to the eyes, and that the tree was desirable as a source of wisdom, she took of its fruit and ate. She also gave some to her husband, and he ate.
(ה)ותתן גם לאישה. שֶׁלֹּא תָמוּת הִיא וְיִחְיֶה הוּא, וְיִשָּׂא אַחֶרֶת:
(5) ותתן גם לאשה AND SHE GAVE ALSO TO HER HUSBAND so that she should not die and he remain alive to take another wife (Genesis Rabbah 19:5).
It is worth noting that there are at least 250 manuscripts of Rashi’s commentary, and so there are lots of versions of what he wrote. Some scholars think that 10-30% of what is attributed to him was actually written by students of his, just done in his style. When the printing press came along, it became harder to discern what was his original work. If this interests you, check out:
