In the beginning God created the heavens and the earth.
Rashi's loose translation of Genesis 1:8:
God called the expanse "heaven" because it was made from fire and water. There was evening and there was morning, a second day.
And God called the expanse heaven: Heb. שָׁמַיִם [This is a combination of the words מַיִם שָׂא, bear water (Gen. Rabbah 4:7); שָׁם מַיִם, there is water; אֵשׁ וּמַיִם, fire and water. He mingled them with one another and made the heavens from them (Chag. 12a).
