Let them be for Signs and Seasons

God made the Sun, Moon, and the stars on the fourth day of creation.  It is interesting to me that He said to let them be for "signs" and for "seasons".  However, looking at the Hebrew Lexicon for these two words commands a much deeper meaning that what we might take away from a straight forward reading of the English translations.

Genesis 1:14-19
Then God said, “Let there be lights in the expanse of the heavens to separate the day from the night, and let them be for signs and for seasons and for days and years; and let them be for lights in the expanse of the heavens to give light on the earth”; and it was so. God made the two great lights, the greater light to govern the day, and the lesser light to govern the night; He made the stars also. God placed them in the expanse of the heavens to give light on the earth, and to govern the day and the night, and to separate the light from the darkness; and God saw that it was good. There was evening and there was morning, a fourth day.

Sign
The Hebrew word is 'owth.  Synonyms for this word from the Hebrew lexicon are: "indicator", "marker", or "omen".

Season
The Hebrew word is mow`ed, which means an appointment.  The word was not actually meant to convey these bodies will affect what we know as "seasons" for Spring, Summer, Fall, and Winter.

In other words, these bodies in the heavens were not only meant to give us light, but also to be indicators of divine appointments.  What greater appointment is there than The Coming of the Son of Man?

Matthew 24:29-31
But immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from the sky, and the powers of the heavens will be shaken. And then the sign of the Son of Man will appear in the sky, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of the sky with power and great glory. And He will send forth His angels with a great trumpet and they will gather together His elect from the four winds, from one end of the sky to the other.
