Genesis 1:7
5 God called the light “day” and the darkness “night.” There was evening, and there was morning, marking the first day. 6 God said, “Let there be an expanse in the midst of the waters and let it separate water from water.” 7 So God made the expanse and separated the water under the expanse from the water above it. It was so. 8 God called the expanse “sky.” There was evening, and there was morning, a second day. 9 God said, “Let the water under the sky be gathered to one place and let dry ground appear.” It was so.
Psalm 148:4
2 Praise him, all his angels. Praise him, all his heavenly assembly. 3 Praise him, O sun and moon. Praise him, all you shiny stars. 4 Praise him, O highest heaven and you waters above the sky. 5 Let them praise the name of the Lord, for he gave the command and they came into existence. 6 He established them so they would endure; he issued a decree that will not be revoked.

The fixity of the heavens creates a considerable impression. The stars contribute further to its impressive aspect (Psalm 8:1-3) ... the body of Nut is studded with stars; and Nut appears to have been drawn twice so that special heavens can be reserved, one for the sun and one for the moon. The psalms are also aware of a plural number of heavens (e.g., Psalm 148:4). The lower of the two ladies of heaven represents the heaven of the moon; the upper, as indicated by the two winged suns on her body, is the heaven of the sun ..."
