(ז) וַיִּ֩יצֶר֩ יהוה אֱלֹהִ֜ים אֶת־הָֽאָדָ֗ם עָפָר֙ מִן־הָ֣אֲדָמָ֔ה וַיִּפַּ֥ח בְּאַפָּ֖יו נִשְׁמַ֣ת חַיִּ֑ים וַֽיְהִ֥י הָֽאָדָ֖ם לְנֶ֥פֶשׁ חַיָּֽה׃
(7) God יהוה formed the Human from the soil’s humus, blowing into his nostrils the breath of life: the Human became a living being.
In the following comment, Rashi is addressing the (unstated) question: "Why is וייצר written with two yods (יוֹדִי"ן).
וייצר. שְׁתֵּי יְצִירוֹת, יְצִירָה לָעוֹלָם הַזֶּה וִיצִירָה לִתְחִיַּת הַמֵּתִים, אֲבָל בַּבְּהֵמָה שֶׁאֵינָהּ עוֹמֶדֶת לַדִּין לֹא נִכְתַּב בִּיצִירָתָהּ שְׁנֵי יוֹדִי"ן:
וייצר AND GOD FORMED — Here the letter yod is written twice to intimate that there were two formations — a formation of man for this world, and a formation of man for resurrection; in the case of animals, however, which will not stand after death for judgment before God the word referring to their formation— ויצר —(Genesis 2:19) is not written with two yods (Midrash Tanchuma, Tazria 1).
Helpful hint: This comment moves through the days of creation. After talking about יוֹם רִאשׁוֹן, Rashi uses ordinal numbers to identify the subsequent days (e.g. בשני)
ויפח באפיו. עֲשָׂאוֹ מִן הַתַּחְתּוֹנִים וּמִן הָעֶלְיוֹנִים, גוּף מִן הַתַּחְתּוֹנִים וּנְשָׁמָה מִן הָעֶלְיוֹנִים, לְפִי שֶׁבְּיוֹם רִאשׁוֹן נִבְרְאוּ שָׁמַיִם וָאָרֶץ, בַּשֵּׁנִי בָּרָא רָקִיעַ לָעֶלְיוֹנִים, בַּשְּׁלִישִׁי תֵּרָאֶה הַיַּבָּשָׁה לַתַּחְתּוֹנִים, בָּרְבִיעִי בָּרָא מְאוֹרוֹת לָעֶלְיוֹנִים, בַּחֲמִישִׁי יִשְׁרְצוּ הַמַּיִם לַתַּחְתּוֹנִים, הֻזְקַק בַּשִּׁשִּׁי לִבְראוֹת בּוֹ בָעֶלְיוֹנִים וּבַתַּחְתּוֹנִים, וְאִם לָאו יֵשׁ קִנְאָה בְמַעֲשֵׂה בְרֵאשִׁית, שֶׁיִּהְיוּ אֵלּוּ רַבִּים עַל אֵלּוּ בִּבְרִיאַת יוֹם אֶחָד:
ויפח באפיו AND BREATHED INTO HIS NOSTRILS — He made him of both, of earthly and of heavenly matter: the body of the earthly, and the soul of the heavenly. For on the first day were created heaven and earth, on the second, He created the firmament for the heavenly beings, on the third He said, “Let the dry land appear” — for the earthly beings, on the fourth He created the lights for the heavenly beings, on the fifth He said, “Let the waters swarm…” — for the earthly beings. Consequently on the sixth there had to be created a being composed of both, of heavenly and of earthly matter, for otherwise there would have been envy (lack of harmony) among the works of Creation, in that there would have been devoted to one class of them one day more of the Creation than to the others (Genesis Rabbah 12:8).
Helpful hint:
The use of the word לְשׁוֹן in the phrase, יְצִירָה זוֹ לְשׁוֹן רִדּוּי וְכִבּוּשׁ is a common way of saying "this word/phrase implies or connotes . . .
וַיִּ֩צֶר֩ יהוה אֱלֹהִ֜ים מִן־הָֽאֲדָמָ֗ה כׇּל־חַיַּ֤ת הַשָּׂדֶה֙ וְאֵת֙ כׇּל־ע֣וֹף הַשָּׁמַ֔יִם וַיָּבֵא֙ אֶל־הָ֣אָדָ֔ם לִרְא֖וֹת מַה־יִּקְרָא־ל֑וֹ וְכֹל֩ אֲשֶׁ֨ר יִקְרָא־ל֧וֹ הָֽאָדָ֛ם נֶ֥פֶשׁ חַיָּ֖ה ה֥וּא שְׁמֽוֹ׃
And God יהוה formed out of the earth all the wild beasts and all the birds of the sky, and brought them to the Human to see what he would call them; and whatever the Human called each living creature, that would be its name.
וייצר מן האדמה. וּבְדִבְרֵי אַגָּדָה יְצִירָה זוֹ לְשׁוֹן רִדּוּי וְכִבּוּשׁ, כְּמוֹ כִּי תָצוּר אֶל עִיר (דברים כ"ד), שֶׁכְּבָשָׁן תַּחַת יָדוֹ שֶׁל אָדָם (בראשית רבה):
ויצר מן האדמה NOW OUT OF THE GROUND THE ETERNAL GOD HAD FORMED — The formation spoken of here is the creation mentioned above (1:25) “And God made the beast of the earth etc.” and this statement comes (is repeated) here to point out that the fowls were created from the swamps; for above it is said that they were created from the waters and here it states that they were created from the earth. Furthermore it teaches you here that when they were created, immediately — on the very same day — He brought them to Adam to give them names (Chullin 27b); and in the statement of the Agada (Genesis Rabbah 17:4) we are told that this expression יצירה means domination and subjugation, like (Deuteronomy 20:19) כי תצור אל עיר “when thou shalt besiege a city", for He subjugated them under the power of Adam.
