Dan 7:25 And he shall speak [great] words against the most High, and shall wear out the saints of the most High, and think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time.
My understanding of this verse is that the evil one's intention is to change times and laws. Concerning changing laws, HaSatan certainly has distorted God's laws with his deceptions that the Torah has been done away with. Much has been written on this deception and many have rejected the deception and are now following the Torah.
But what is his deception on times? His deception of time is the world's calendar system. In the world's time, the 7 days of the week bear the names of 7 pagan gods. It runs continuously and is artificial, man-made. Nothing in creation declares this week.
The truth of the matter is that Yahweh completed all of his works in six days and rested on the seventh. He set apart a holy time, a time which belongs to Him, but is created for us, His Holy People. Creation declares this week, especially the light from the sun and the moon.
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: And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so. (Gen 1:14-15)
Now the word translated in KJV for seasons (Strong's H4150) is mow'ed, Hebrew for appointed set time, appointed place, appointed meeting. The world's calendar of months does not follow the lunar month, for its months are again artificial, man-make. The world's calendar hacks the month unnaturally into a solar year. Yahweh's way of observing a new year with the barley aviv is natural, lining up with His creation and bounty. With Yahweh's way, most years will have twelve months, and occasionally there will be an extra month. It is not unnatural to have an extra month, it is the way Our Creator designed the times and the seasons. It is a blessing to have an extra month to allow us extra time for reflection and repentance prior to the beginning of the feast days. The lunar months require this extra month to keep the natural order with the sun. The yearly feasts are observed in this manner.
Just as extra months are part of Our Creator's plan, His Weeks also are designed for extra days reflection and repentance. The world's system of weeks does not allow for this time and is not in the natural order. The deception of the world's week is so strong and takes so much power to overcome that I am sure you will reject the truth of Yahweh's week the first time you read or hear it. I did. I ask that you take a break from reading now and ask humbly that Ruach HaKodesh guide you in all truth. This truth disarms the evil one and he is going to give a fight, but he is overcome. This is a truth for the remnant and is necessary for our reunification. Please pray, and then pray some more.
And the LORD spake unto Moses, saying, Speak thou also unto the children of Israel, saying, Verily my sabbaths ye shall keep: for it [is] a sign between me and you throughout your generations; that [ye] may know that I [am] the LORD that doth sanctify you. Ye shall keep the sabbath therefore; for it [is] holy unto you: every one that defileth it shall surely be put to death: for whosoever doeth [any] work therein, that soul shall be cut off from among his people. Six days may work be done; but in the seventh [is] the sabbath of rest, holy to the LORD: whosoever doeth [any] work in the sabbath day, he shall surely be put to death. Wherefore the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, [for] a perpetual covenant. It [is] a sign between me and the children of Israel for ever: for [in] six days the LORD made heaven and earth, and on the seventh day he rested, and was refreshed. Ex 31:12-17
First let me explain that a day begins at evening at sunset and ends at the next sunset. This was established in creation week - "And the evening and the morning were the first day" ,And the evening and the morning were the second day", etc...
The first day of the month is the first sighted crescent moon. The new crescent moon is only visible for a short time immediately after sunset. That is the first day of the new month. This first day through the sixth day are work days. Then the seventh day is the Sabbath. Then six more days (8th - 13th) are work days. Then the seventh day (14th of the month) is the second Sabbath of the month. Then six more days (15th-20th) and then the third Sabbath is the 21st of the month. Then a final six days of the month (22nd - 27th) then the last Sabbath of the month starts on the 28th. The last Sabbath is always at least 2 days and often a 3rd day. It concludes when there is a sighted crescent moon. When the moon is sighted, it starts a new month at day one. It's back to work when the crescent moon is sighted or when there have been 3 days in the Sabbath.
The moon is a quarter moon on the 7th of the month, full on the 14th of the month, last quarter on the 21st of the month, and is not visible on the 28th. The Sabbath continues for 2 or 3 days while the moon is not visible. The moon is a calendar in the sky for the appointed time, just as Genesis 1:14 says the moon was created to be a sign for the appointed times (The Sabbath!).
