"And God called the dry land Earth" (Genesis 1:10) - which was eager to do the will of its Maker. Rabbi Yitzchak says: "I am El Shaddai" - I am the One who said to My world, Dai [Enough], for had I not done so, heaven and earth would still be stretching and extending on and on. "And the gathering of the waters He called Seas." But is it not a single sea? Rather, the fish that comes up from Acco and Sidon is not like the one that comes up from Spain.
The God Who Told His Expanding World Enough
Yalkut Shimoni on Torah 8:1
(בראשית א י) וַיִּקְרָא אֱלֹהִים לַיַּבָּשָׁה אֶרֶץ שֶׁרָצְתָה לַעֲשוֹת רְצוֹן קוֹנָהּ רַבִּי יִצְחָק אוֹמֵר, "אֲנִי אֵל שַׁדַּי", אֲנִי הוּא שֶׁאָמַרְתִּי לְעוֹלָמִי דַּי, שֶׁאִלּוּ לֹא כֵן עֲדַיִן הָיוּ שָׁמַיִם וָאָרֶץ נִמְתָּחִין וְהוֹלְכִין. וּלְמִקְוֵה הַמַּיִם קָרָא יַמִּים, וַהֲלֹא יָם אֶחָד הוּא אֶלָּא אֵינוֹ דּוֹמֶה דָּג הָעוֹלֶה מֵעַכּוֹ וּמִצִּידֹן לְעוֹלֶה מֵאַסְפַּמְיָא.
