Exodus 12:3 ~ ... on the tenth of this month each family shall take a lamb into their household... a lamb without blemish, a yearling male from either the sheep or the goats. Keep watch over it until the 14th day; and then all the assembled congregation of (Set Apart believers) shall slaughter them at twilight. They shall take some of the blood and put it on the two doorposts and the lintel of the houses in which they are to eat it. They shall eat it the same night, roasted over the fire, with unleavened bread and with bitter herbs. Do not leave anything left over until morning, but if there are leftovers, burn them. Be fully dressed and ready to leave before you eat and eat quickly: it is a passover offering to YHWH as protection, because that night He will go through the land of Egypt and strike down every first born, both man and beast; and He will mete out punishments to all the 'gods' of Egypt because He alone is Elohim. The blood on the houses shall be a sign for you: when Yah sees it He will pass over you so that no plague will destroy you when He strikes the land of Egypt.
Exodus 12:15 ~ Seven days you shall eat unleavened bread... on the very 1st day (of the 7 days) you shall remove leaven from your houses... The first day and the seventh day are sacred occasions and no work is to be done, only whatever is to be eaten may be prepared.
Exodus 12:17 ~ You shall observe the Feast of Unleavened Bread for on this very day (the 15th day of the 1st month) I brought you out of Egypt, to be observed throughout the ages as an institution for all time.
Exodus 12:18 ~ In the first month from the 14th day at evening you shall eat unleavened bread until the 21st day of the month at evening. No leaven is to be found in your houses - whether one is a stranger or a citizen of the country you shall eat nothing leavened.
Exodus 12:24 ~ You shall observe this as an institution for all time, for you and for your descendants. And when you enter the land that I will give you, as I promised, you shall observe this rite... And when your children ask why and what does it mean, you shall say, 'It is the passover sacrifice to YHWH Elohim because He passed over the houses of the (descendants of Jacob and the mixed multitude) in Egypt when He smote the Egyptians, but saved our houses'.
In Leviticus we are reminded:
Leviticus 23:4 ~ These are the set times of YHWH, the sacred occasions, which you shall celebrate each at its appointed time: In the first month, on the 14th day of the month, at twilight, there shall be a passover offering to YHWH and on the 15th day of that month YHWH's Feast of Unleavened Bread... for seven days.
And again in Deuteronomy 16 we read that a passover offering is made to YHWH and slaughtered in the place Elohim will choose to establish His Name - For 7 days no leaven shall be found among you. You cannot slaughter the sacrifice wherever you choose but only at the place YHWH chooses to establish His Name. In the morning you may start back home - on the 7th day of Unleavened Bread hold a solemn gathering, do no work.
His people are instructed to do this so they remember the day of their departure from the land of Egypt for as long as they live. The blood of the lamb was a sign to YHWH and saved them from death - they were set free from being slaves to Pharaoh. In modern times our acceptance of the shed blood of His Son is also a sign to YHWH, and sets us free from our old sin-nature, saving us from death eternal.
These quotes from Scripture establish the fixed time of when to observe the Feast of Unleavened Bread, which begins immediately after the the twilight meal of the roasted lamb: the passover offering. That is how it was done originally and for the purpose of being set free from Pharaoh. The blood of the lamb was the sign and anyone gathered together to eat in a household whose lintel and doorposts were painted with this blood were passed over by the Angel of Death. The Hebrew descendants of Jacob along with a mixed multitude who chose YHWH as their "God" left the next day. We, however, in today's world are no longer required to make a "passover offering" to YHWH because the death of His Son supplanted that rite. We should not imagine that we are to substitute any other behaviors on the evening of the 14th day of the first month.
In Numbers Chapter 9 we learn of an exception added by YHWH concerning those who might be unclean because of handling a dead body or might be traveling. Under these two circumstances one was allowed to make a passover offering during the second month.
Numbers 9:9 ~ Yah said to Moses, “Tell the Israelites: When any one of you or your descendants is unclean because of a dead body, or is away on a journey, he may still observe the Passover. Such people are to observe it at twilight on the fourteenth day of the second month. They must observe the Passover according to all its statutes. But the man who is ceremonially clean, is not on a journey, and still fails to observe the Passover, is to be cut off from his people, because he did not present Yah’s offering at its appointed time. That man will bear the consequences of his sin. If a foreigner dwelling among you wants to observe the Passover offering to YHWH, he is to do so according to the Passover statute and its ordinances. You are to apply the same statute to both the foreigner and the native of the land.”
Again I point out that the passover offering is no longer required, so one being unclean or traveling during the 14th day of the first month would not need to observe 'passover' a month later. Remember: Yah said this offering was brought to and slaughtered in the place He will choose to establish His Name - You cannot slaughter the sacrifice wherever you choose but only at the place YHWH chooses to establish His Name. The last place He chose to establish His Name was Jerusalem in general and at the temple specifically where the priest would handle offerings etc.... and as we know none of that exists today but it is still the last place we know of where our Creator established His Name.
For us to observe this Set Apart time of Yah's in today's world, we simply remember that with a mighty hand YHWH frees us from bondage to sin, that hand being His Son who shed his blood for our sake. The following seven days we can choose not to eat anything that has been leavened; symbolically recognizing the true bread from heaven, Y'shua the Anointed One in which no leaven (sin) was found, The Lamb without blemish. We keep the first day and the seventh day as sacred occasions, which means the 14th day is a regular day of rest followed by the 15th day which is the first day of unleavened bread, and then the 21st day which is a double: regular seven day count for the day of rest and the last day of Unleavened Bread. We do this to remember what our Creator did to set His people free back in the day and what He did to set us free in the renewed covenant. If we accept the shed blood of Yahshua as a covering for our old sin nature which releases us from bondage to sin, we will be protected from eternal death. We will be gathered together and saved from the final 7 plagues to be poured out upon the earth. As it was in the beginning, so shall it be at the end:

He will go through the (whole earth) .... and He will mete out punishments to all the 'gods' of (the world) because He alone is Eloah. The blood (of His Son) shall be a sign for you: when Yah sees it (on our hearts) He will pass over you so that no plague will destroy you (after Y'shua returns at the sounding of the 7th trumpet).Hebrews 10 (lightly paraphrased- Dusty)
We choose to accept Y'shua as our High Priest who offered a one time sacrifice for sins, who sits forever at the right hand of the Father where he waits until his foes are placed as a footstool under his feet. For, by one offering (himself), he has perfected forever them who are sanctified (set apart) by him. And the Set Apart Spirit also testifies to us by saying: This is the covenant which I will give them after those days, says Master YHWH: I will put my Instructions into their minds and inscribe it on their hearts and their iniquity and their sins I will not remember against them. Now, where there is a forgiveness of sins there is no offering for sin demanded. We have therefore my Brothers assurance of entering into the sanctuary by the blood of Yahshua and by a path of life.
