And he shall speak words against the Most High, and shall wear out the saints of the Most High, and shall think to change times and law. Daniel 7:25 Brenton
Can man change times and law?
Of course! According to Daniel 7:25.
Does God approve of the changes? Not all! Because when He became flesh, Jesus emphasized in Matthew 5:17-18, Luke 16:17 that His Words can never be changed.
Can the Jews change the time or at any time decide to change the time of Jesus that is set in Genesis? Of course!
Does Jesus approve of their change? Of course not!
Does the fact that someone has changed the law and the times of God affect the times and the law of Jesus? Not at all, because no one may change the times and law of Jesus (who is God of Abraham, Isaac, Jacob, and Moses) and if it happens, we full believers in Jesus must follow after Jesus.
Are we required to keep the time of God in dealing with Him? Most definitely, because we have decided to follow His Universal Culture as given to Moses and guarded by the Prophets.
Are we allowed to adjust God's time or words for our convenience in belief or in whatever else? No, if we are to be obedient children of Elohim. Anyone who engages in changing whatsoever in the Words of Jesus does that at his/her own peril at the judgment day.
With that in mind, let us delve into the 7 days of the Passover week, 7 days which encompass 8 calendar days.
18 Beginning the fourteenth day of the first month, ye shall eat unleavened bread from evening, till the twenty-first day of the month, till evening.
19 Seven days leaven shall not be found in your houses; whosoever shall eat anything leavened, that soul shall be cut off from the congregation of Israel, both among the occupiers of the land and the original inhabitants.
Exodus 12:18-19 Brenton
Exodus 12:18-19 KJ3
(18) In the first month, on the fourteenth day of the month, at evening you shall eat unleavened bread, until the twenty-first day of the month, at evening. (19) For seven days no leaven shall be found in your houses. For anyone eating any leaven, that soul shall be cut off from the congregation of Israel, among the aliens, and among the natives of the land.
Leviticus 23:5-8 KJ3
(5) In the first month, on the fourteenth of the month, between the evenings is the Passover to Jehovah. (6) And on the fifteenth of this month is the Feast of Unleavened Bread to Jehovah; you shall eat unleavened things seven days. (7) On the first day you shall have a holy gathering; you shall do no work of service; (8) and you shall bring near a fire offering to Jehovah seven days; and the seventh day shall be a holy gathering; you shall do no work of service.
