תדשא הארץ דשא עשב. לֹא דֶּשֶׁא לְשׁוֹן עֵשֶׂב וְלֹא עֵשֶׂב לְשׁוֹן דֶּשֶׁא, וְלֹא הָיָה לְשׁוֹן הַמִּקְרָא לוֹמַר תַּעֲשִׂיב הָאָרֶץ, שֶׁמִינֵי דְּשָׁאִים מְחֻלָּקִין, כָּל אֶחָד לְעַצְמוֹ נִקְרָא עֵשֶׂב פְּלוֹנִי, וְאֵין לָשׁוֹן לַמְדַבֵּר לוֹמַר דֶּשֶׁא פְּלוֹנִי, שֶׁלְּשׁוֹן דֶּשֶׁא הוּא לְבִישַׁת הָאָרֶץ כְּשֶׁהִיא מִתְמַלֵּאת בִּדְשָׁאִים: תדשא הארץ דשא עשב THE EARTH SHALL SPROUT FORTH SPROUTS, HERB — דשא does not mean the same as עשב nor does עשב mean the same as דשא so that it is not a correct expression in Biblical Hebrew to say תעשיב הארץ, for the species of דשא are all different, each by itself being called this or that עשב, and it would not be linguistically correct for a speaker to say this or that דשא, for by דשא is meant that which forms the covering of the ground when it is filled with herbage.
תדשא הארץ. תִּתְמַלֵּא וְתִתְכַּסֶּה לְבוּשׁ עֲשָׂבִים. בִּלְשׁוֹן לַעַז נִקְרָא דֶּשֶׁא ארבריץ, כֻּלָן בְּעִרְבּוּבְיָא, וְכָל שֹׁרֶשׁ לְעַצְמוֹ נִקְרָא עֵשֶׂב: תדשא הארץ THE EARTH SHALL SPROUT FORTH [SPROUTS] — Let it be filled and covered with a garment of different grasses. In old French דשא is called herbaries; English herbage, meaning all species of herbs growing together collectively whilst each root by itself is called an עשב.
מזריע זרע. שֶׁיְּגַדֵּל בּוֹ זַרְעוֹ לִזְרֹעַ מִמֶּנוּ בְּמָקוֹם אַחֵר: — מזריע זרע YIELDING SEED — that its seed should grow within itself, so that some of it may be sown in another spot.
עץ פרי. שֶׁיְּהֵא טַעַם הָעֵץ כְּטַעַם הַפְּרִי, וְהִיא לֹא עָשְׂתָה כֵן, אֶלָּא וַתּוֹצֵא הָאָרֶץ עֵץ עוֹשֶׂה פְּרִי וְלֹא הָעֵץ פְּרִי, לְפִיכָךְ כְּשֶׁנִּתְקַלֵּל אָדָם עַל עֲוֹנוֹ נִפְקְדָה גַם הִיא עַל עֲוֹנָהּ וְנִתְקַלְּלָה: עץ פרי FRUIT TREE — that the taste of the tree be exactly the same as that of the fruit. It did not, however, do this, but (v. 12) “the earth brought forth a tree yielding fruit” and the tree itself was not a fruit; therefore when Adam was cursed on account of his sin, it (the earth) was also visited (because of its sin) and was cursed also (Genesis Rabbah 5:9).
אשר זרעו בו. הֵן גַרְעִינֵי כָל פְּרִי שֶׁמֵּהֶן הָאִילָן צוֹמֵחַ כְּשֶׁנּוֹטְעִין אוֹתוֹ: אשר זרעו בו WHOSE SEED IS IN ITSELF — This refers to the kernels of each kind of fruit from which the tree grows when they are planted.
