Genesis 1:10

קרא ימים CALLED HE SEAS — But does it not form one great sea? But it speaks of seas because the taste of fish which comes up from the sea at Acco is not the same as the taste of fish which comes up from the sea at Aspamia (Genesis Rabbah 5:8).

וַיִּקְרָ֨א אֱלֹהִ֤ים ׀ לַיַּבָּשָׁה֙ אֶ֔רֶץ וּלְמִקְוֵ֥ה הַמַּ֖יִם קָרָ֣א יַמִּ֑ים וַיַּ֥רְא אֱלֹהִ֖ים כִּי־טֽוֹב׃

And God called the dry land Earth; and the gathering together of the waters He called Seas: and God saw that it was good.
