If you read the LXX, there too we see that the daylight portion of the 24 hour cycle was created prior to the Night time portion of the 24 hour cycle.
The Greek reads in like manner for we see the word, fws (light) was named hmeran day and the skotoV darkness He named nukta (night) and then it became espera (twilight) and then it became prwi morning, hmera mia (Day One).
Now, never ever can the espera mean the night and never ever can the prwi mean day. Likewise, never ever can fws mean dawn nor can nukta mean sunset.
In Hebrew Yown can mean the 24 hour cycle and also the day portion of that cycle, just as it can in English, and I believe this has come to be because the night is not the dominant portion of the cycle. Be that as it may, in Hebrew erev can never mean layil and boqer can never mean Yown. Just like in English dawn can never mean day and night can never mean sunset.
It would have been nice to have left all the confusing doctrine behind. I wont want anyone to be too overwhelmed though, I look at it in this way. We take on one issue at a time. It is after all, a sanctification process.
Obviously Jesus never kept the Sabbath incorrectly, quite the contrary, He demonstrated for us a liberalization which allows us to move freely without the instructions of those who consider themselves as THE authorities on these matters. The Messiah would have followed what was the right method of keeping the Sabbath and obviously if one does not have hydro, sunset would be the close of ones business.
Therefore it stands to reason that when the sun went down, in fact prior to, all Gods people would ready themselves for the following day. After all, that is why Friday can also be consider Preparation Day. We have many Sabbaths and many preparation days through-out the year.
As for the Day of Atonement, it too can be considered as a Sabbath. However it differs in many ways in comparison. For instance, rather than a feast day, it is a day of fasting. In stead of a day of celebration, it is a day of mourning. So, not only are we not permitted to work on that day, but as you can see, this Rest day has many differences last of which, it starts on the day preceding the 10th day of Abib.
I see the reasoning behind this for in prescribing this day in the way it is, it would cause the adherent to not eat after sunset on the 9th, go hungry all day of the 10th, go to bed hungry on the evening of the 10th, and thus, have an entire cycle of eating taken away from the child of God. After all, is a one day fast really that much to ask from God?
If one were to start the day of Atonement at sunset the first night, and shortly thereafter go to sleep. The next Morning one might have the habit of skipping breakfast and well if you are skipping breakfast normally how are you denying yourself so far. So lunch comes around and you might be hungry but not starving, so therefore so far you have only denyed yourself of one meal. And then comes sunset at which time you would be free to eat again? How is it that you have denied yourself? You have missed one meal. Did the Israelites not go through more pain then this? Should you be let off so easy? No.
The day of Atonement is meant for you to deny yourself for one day. It is more sensible to start the first night at around 6:00 or shortly thereafter (around dinner time). Once done dinner then do not eat until the morning after the tenth day of the month. Then you would have missed three meals and denied yourself one full day. If you eat at 6:00p.m. on the ninth, and then again at 6:01p.m. on the tenth, you have not even gone without eating for 24 hours, because no body eats every hour of the day.
To translate a day as the darkness teachers prescribe, one could feasiblely eat at say 6:00 Oclock on the 9th, and then again at 6:01 p.m on the 10th. Now for those who eat only a single meal a day, they wont even have suffered in the least. Those who eat twice a day, too would hardly have noticed an interruption in the days cycle.
Lastly, the Commandment clearly teaches us that we are to start the sabbath of Atonement on the ninth. The sunset clearly belongs to the ninth day and not as the kick-off to the 10th otherwise it would have been written in this manner;
Leviticus 23:32 It shall be unto you a sabbath of rest, and ye shall afflict your souls: in the tenth day of the month at even, from even unto even, shall ye celebrate your sabbath. (KJV)
