Kejadian 1:18

1:18 to preside over the day and the night, and to separate the light from the darkness. ¹  God saw that it was good.

Kejadian 1:25

1:25 God made the wild animals according to their kinds, the cattle according to their kinds, and all the creatures that creep along the ground according to their kinds. God saw that it was good.

[1:18]  ¹ sn In days one to three there is a naming by God; in days five and six there is a blessing by God. But on day four there is neither. It could be a mere stylistic variation. But it could also be a deliberate design to avoid naming “sun” and “moon” or promoting them beyond what they are, things that God made to serve in his creation.
