¹³ And there was evening and there was morning, the third day.

¹⁴ And God said, “Let there be lights in the dome of the sky to separate the day from the night; and let them be for signs and for seasons and for days and years, ¹⁵ and let them be lights in the dome of the sky to give light upon the earth.” And it was so.
