Passage
And God called the firmament, Heaven; and the evening and morning were the second day.
And God called the firmament, Heaven; and the evening and morning were the second day.
Genesis 1:6 And God said: Let there be a firmament made amidst the waters: and let it divide the waters from the waters.
Genesis 1:7 And God made a firmament, and divided the waters that were under the firmament, from those that were above the firmament, and it was so.
Genesis 1:8 And God called the firmament, Heaven; and the evening and morning were the second day.
Genesis 1:9 God also said; Let the waters that are under the heaven, be gathered together into one place: and let the dry land appear. And it was so done.
Genesis 1:10 And God called the dry land, Earth; and the gathering together of the waters, he called Seas. And God saw that it was good.
The verse centers on "called", "firmament", "heaven", "evening", "morning", and "second". It is saying that the verse draws attention to "called" and "firmament", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 7's "And God made a firmament and divided..." into verse 9's "God also said Let the waters that...", so "called" and "firmament" belong inside that flow. In Genesis context, the local focus is creation, human rebellion, covenant promise, and God's providence.
A plain takeaway is to answer the verse's own emphasis on "called" and "firmament" with trust shaped by these words, not by a vague optimism outside the passage.
