Genesis 1:19
And the evening and the morning were the fourth day.
Cross-reference
Genesis 1:5
Parallel
Genesis 1:5 established the 'evening and morning' formula marking each creation day. Here it recurs as the fourth day closes with the same refrain.
Genesis 1:8
Parallel
Genesis 1:8 uses the same 'evening and morning' formula for the second day. The repeated refrain ties each creation day into a unified literary structure.
Genesis 1:31
Parallel
In Genesis 1:31, this same evening-morning formula reaches its climax as God declares everything 'very good' — the pattern begun here culminates on the sixth day.
