In the process of Creation G-d eventually calls names of different things:
וַיִּקְרָא אֱלֹהִים לָאוֹר יוֹם וְלַחֹשֶׁךְ קָרָא לָיְלָה ...׃
God called the light Day, and the darkness He called Night.
וַיִּקְרָא אֱלֹהִים לָרָקִיעַ שָׁמָיִם...׃
God called the expanse Sky.
וַיִּקְרָא אֱלֹהִים לַיַּבָּשָׁה אֶרֶץ וּלְמִקְוֵה הַמַּיִם קָרָא יַמִּים וַיַּרְא אֱלֹהִים כִּי־טוֹב׃
God called the dry land Earth, and the gathering of waters He called Seas. And God saw that this was good.
What does it mean G-d called something a name?
