Passage
And there was evening and there was morning, a fourth day.
And there was evening and there was morning, a fourth day.
Genesis 1:17 And God set them in the firmament of heaven to give light upon the earth,
Genesis 1:18 and to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.
Genesis 1:19 And there was evening and there was morning, a fourth day.
Genesis 1:20 And God said, Let the waters swarm with swarms of living creatures, and let birds fly above the earth in the open firmament of heaven.
Genesis 1:21 And God created the great sea-monsters, and every living creature that moveth, wherewith the waters swarmed, after their kind, and every winged bird after its kind: and God saw that it was good.
The verse centers on "evening", "morning", and "fourth". It is saying that the verse draws attention to "evening" and "morning", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 18's "and to rule over the day and..." into verse 20's "And God said Let the waters swarm...", so "evening" and "morning" 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 "evening" and "morning" with trust shaped by these words, not by a vague optimism outside the passage.
