jerusalem bible (alternative genesis)

God set them in the vault of heaven to shine on the earth, to govern the day and the night and to divide light from darkness. God saw that it was good. Evening came and morning came: the fourth day.

On the High Wall, the Shining Ones observed them as they shone on the land, ruling day and night, and distinguishing between light and darkness. The Shining Ones saw how suitable they were. There was evening and there was morning - a fourth day [stage].
