Genesis 1:14

1:14 And God said, Let there be {k} lights in the firmament of the heaven to {l} divide the day from the night; and let them be for {m} signs, and for seasons, and for days, and years:

(k) By the lights be means the sun, the moon, and the stars.

(l) Which is the artificial day, from the sun rising, to the going down.

(m) Of things belonging to natural and political orders and seasons.
