The Talmud teaches that three partners participate in the creation of a human being — God, father, and mother — and elaborates on why humans were created last among the creatures, suggesting purposefulness in the design of creation.
תָּנוּ רַבָּנַן: שְׁלֹשָׁה שׁוּתָּפִין יֵשׁ בָּאָדָם — הַקָּדוֹשׁ בָּרוּךְ הוּא, וְאָבִיו, וְאִמּוֹ. אָבִיו מַזְרִיעַ הַלּוֹבֶן, שֶׁמִּמֶּנּוּ עֲצָמוֹת, וְגִידִים, וְצִפׇּרְנַיִם, וּמוֹחַ שֶׁבְּרֹאשׁוֹ, וְלוֹבֶן שֶׁבָּעַיִן. אִמּוֹ מַזְרַעַת אוֹדֶם, שֶׁמִּמֶּנּוּ עוֹר, וּבָשָׂר, וּשְׂעָרוֹת, וְשָׁחוֹר שֶׁבָּעַיִן. וְהַקָּדוֹשׁ בָּרוּךְ הוּא נוֹתֵן בּוֹ רוּחַ, וּנְשָׁמָה, וּקְלַסְתֵּר פָּנִים, וּרְאִיַּית הָעַיִן, וּשְׁמִיעַת הָאוֹזֶן, וְדִבּוּר פֶּה, וְהִלּוּךְ רַגְלַיִם, וּבִינָה, וְהַשְׂכֵּל. דָּרֵשׁ רַבִּי אֲבָהוּ: מַאי דִכְתִיב ״מִי מָנָה עֲפַר יַעֲקֹב וּמִסְפָּר אֶת רוֹבַע יִשְׂרָאֵל״? מְלַמֵּד שֶׁהַקָּדוֹשׁ בָּרוּךְ הוּא יוֹשֵׁב וְסוֹפֵר אֶת רְבִיעִיּוֹתֵיהֶם שֶׁל יִשְׂרָאֵל, מָתַי תָּבֹא טִיפָּה שֶׁהַצַּדִּיק נוֹצָר הֵימֶנָּה.
§ The Sages taught: There are three partners in the creation of a person: The Holy One, Blessed be He, and his father, and his mother. His father emits the white seed, from which the following body parts are formed: The bones, the sinews, the nails, the brain that is in its head, and the white of the eye. His mother emits red seed, from which are formed the skin, the flesh, the hair, and the black of the eye. And the Holy One, Blessed be He, inserts into him a spirit, a soul, his countenance [ukelaster], eyesight, hearing of the ear, the capability of speech of the mouth, the capability of walking with the legs, understanding, and wisdom. Rabbi Abbahu taught: What is the meaning of that which is written in Balaam’s blessing: “Who has counted the dust of Jacob, or numbered the stock [rova] of Israel” (Numbers 23:10)? The verse teaches that the Holy One, Blessed be He, sits and counts the times that the Jewish people engage in intercourse [revi’iyyoteihem], anticipating the time when the drop from which the righteous person will be created will arrive.
