Hi daqq,
I was reading the other night, where Jesus said "are there not 12 hours in a day" and I thought then that Jesus is only including daytime hours where there is light and I also thought then that even Jesus didn't refer naturally to a 24 hour day. But rather the hours wherein there is light. Thanks for explaining the Roman calender, I didn't know that, but I know that God is light, and in him there is no darkness at all, and I know that he doesn't bring life through darkness only light, and he brings us from darkness into light thus we have the evening and the morning in each day in creation to bring the works of God to be made manifest in the morning which is the first light. We are the darkness that God works through, we were in darkness before we knew him. And just as the moon being a dead planet only reflects the light of the sun, to bring light onto the earth whilst it is in darkness, so is it with God's people, they are in darkness until God brings them to life through Christ and the light is then reflected through them, through the son, to bring light to those in darkness in the earth.
God forms and works in us as we were hear the word through those who are born of him, they are like lamp posts bringing light on a dark night to guide us and teach the way of Christ, a bit of light whilst we are in the darkness, then once we obey the teachings and start live by the will of God, in God's time we are blessed with the Spirit, and this is the beginning for us when Christ enters into our hearts, he is our first light. Then we start to be changed, becoming a new man through Christ, through progressive revelation, progressive light and God changes our hearts to be more like his son through faith by the grace of God.
I know the scriptures speak of the natural, but many don't seem to see the spiritual. And I know that God's ways and times aren't our ways and times. But it's simple, the old testament puts to death, and the New testament brings life after death through Christ Jesus he is the way, the truth and the life and no one comes to the father except through him.
The first hour of the day is called Yom haRishon in Num7:12. That is typically the hour in which the sun would rise. However the first hour of the prayer times is more important and called Yom Echad, which is what we find in Gen1:5, and that is the reason for the wording "and there was evening, and there was morning", because the hours of prayer commenced at the bottom of the hour. The first hour of prayer, (Yom Echad), commenced at the bottom of the third hour of the day on the sundial, (such as the sundial of Ahaz). The sixth hour of the day was also an hour of prayer, commencing at the bottom or "evening" portion of the sixth hour of the day. The ninth hour of the day was also the last official hour of prayer for the day; and it likewise commenced at the bottom or evening portion of the hour. The tenth hour of the day is the daily Shabbat hour but in the prayer times it is not the tenth but the seventh hour because of the offsetting of the prayer times being commenced in the third hour of the day on the sundial.
Yom haRishon, (Num 7:12) = first hour of the day by the sundial.
Yom Echad, (Gen 1:5) = bottom of the third hour to the bottom of the fourth hour of the day.
That is why Rev 8:1 speaks of silence in heaven for the space of half an hour; for such language informs the reader that what follows pertains to the daily hours of the prayer times. The shabuim-weeks of Daniel pertain to these same prayer times which are three times daily at the half-hour or bottom of the hour: every hour has a morning half and an evening half, just as every second, or minute, or day, for it speaks more in terms such as inhale, exhale, (breathing while speaking, spoken-Word, just as we have in Gen1).
