Genesis 1
14 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:
15 And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.
16 And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.
17 And God set them in the firmament of the heaven to give light upon the earth,
18 And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.
19 And the evening and the morning were the fourth day.
God creates the heavenly bodies on the fourth day and they are identified as lights in the sky. These lights or starts have their own functions as God has ordained in His creation pattern. They are for:
- signs - indicators of events and messages
- seasons - indicators of appointed times for earthly purposes like farming, travelling, birth, death, etc.
- days - separator of days in addition to the evening and morning rotation of the earth
- years - indicator of counting years
Then the purpose of the sun (the greater light) and the moon (the lesser light) for lighting the day and night.
