Genesis 1:17-18

1:17 God placed the lights in the expanse of the sky to shine on the earth, 1:18 to preside over the day and the night, and to separate the light from the darkness. God saw that it was good.

tn Heb “them”; the referent (the lights mentioned in the preceding verses) has been specified in the translation for clarity.

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.
