Since the meaning of the 2,300 evenings and mornings from Daniel 8 comes into view in some other threads, I want to give an interesting explanation on this I recently found in two different places, given by obviously two different people.
The interpretation given here is in most parts taken from Dan Bruce's freely available book "
Daniel Unsealed".
Though I do not agree with all of his writings, this part seems to hold some water.
Daniel 8 (NIV)
13 Then I heard a holy one speaking, and another holy one said to him, “How long will it take for the vision to be fulfilled—the vision concerning the daily sacrifice, the rebellion that causes desolation, the surrender of the sanctuary and the trampling underfoot of the Lord’s people?”
14 He said to me, “It will take 2,300 evenings and mornings; then the sanctuary will be reconsecrated.”
15 While I, Daniel, was watching the vision and trying to understand it, there before me stood one who looked like a man.
16 And I heard a man’s voice from the Ulai calling, “Gabriel, tell this man the meaning of the vision.”
17 As he came near the place where I was standing, I was terrified and fell prostrate. “Son of man,”2 he said to me, “understand that the vision concerns the time of the end.”
One key is the (probably mis-)translation of evenings - mornings as days in the KJV and several other translations.
The Hebrew bible speaks of erev-boker ערב בקר (Strong’s OT: 1242, 6153). Looking for a proper interpretation of this phrase we find
in Exodus 27:12 “evening-morning” is used to designate an evening-until-morning period, or, in other words, a night.
What night is this verse speaking of?
Exodus 12 (KJV)
6 And ye shall keep it up until the fourteenth day of the same month: and the whole assembly of the congregation of Israel shall kill it in the evening.
7 And they shall take of the blood, and strike it on the two side posts and on the upper door post of the houses, wherein they shall eat it.
8 And they shall eat the flesh in that night, roast with fire, and unleavened bread; and with bitter herbs they shall eat it.
9 Eat not of it raw, nor sodden at all with water, but roast with fire; his head with his legs, and with the purtenance thereof.
10 And ye shall let nothing of it remain until the morning; and that which remaineth of it until the morning ye shall burn with fire. Passover, the annual memorial of the Jewish people, is defined as an evening-until-morning event (a night) to be observed once a year.
Thus, “evening-morning” does not represent a 24-hour day, nor does it have anything to do with the morning and evening sacrifices, but instead it means a night.
More specifically, it means the Passover night, the annual reminder of God’s redemption of Israel. So, 2,300 “evening-morning(s)” in the prophecy represents 2,300 Passover nights in history.
Another important point ist the scope of the question asked in verse 13,
“How long shall be the vision concerning the daily sacrifice, and the transgression of desolation, to give both the sanctuary and the host to be trodden under foot?” (KJV).
Past expositors have generally misunderstood the scope of the question, assuming it to be asking only how long the interruption
of the sacrifices and other transgressions against the Temple would last. That was not the question being asked, however. The questioner was rhetorically asking about the duration of the events of the entire vision itself. Although not perfect, a better translation of verse 13 reads,
“How long will the events of the vision last, this vision concerning the regular offering and the transgression which is so appalling, that
allows the sanctuary and the army to be trampled underfoot?” (CJB).
That wording recognizes that the question about duration pertains to all of the events in the vision, a time period that includes the events described in verses 1-12 as well as the trampling of the sanctuary underfoot (i.e.,not under Jewish control) that we now know from history continued in one form or another from the Exile in Babylon until June, 1967. When the full scope of the question is understood, it is easy to see that the first action event of the vision, the king of Greece moving against the king of Persia described in verse 6, is the starting point for calculating the duration of the vision. Verse 14 then states that the final event of the vision will come after 2,300 “evening-morning(s)” have occurred.
Putting all of these pieces together, verse 14 is saying that the sanctuary will be restored after 2,300 “evening-morning(s)”, with the count beginning from the time when Alexander the Great first moved against Darius III of Persia, which occurred in the Battle of Granicus in 334 BCE.
The third key to interpretation of the prophecy is to understand how to count the 2,300 Passovers that determine the time span stipulated in verse 14, to know when to begin and when to end the count.
The initial Passover in the count had to occur after the first action event of the prophecy, the Battle of Granicus stipulated in verse 6, had occurred. That battle was the first time that Alexander the Great met and defeated an army of Darius III of Persia.
There is no direct historical reference to a specific date for the Battle of Granicus, but a mention by Plutarch of Chaeronea, who recorded that the battle took place in the Macedonian month Daesius in the year 334 BCE,is sufficient to locate it chronologically.
That reference shows that Alexander moved against the Persians in late May or early June. Passover was celebrated inMarch that year, so it had already occurred before the battle began. Thus, the next Passover, the one celebrated in 333 BCE , is the one that must be used to start the count that determines the duration of the 2,300-Passover time span specified in verse 14.
Equally important, the count has to be concluded before Old Jerusalem and the Temple Mount were liberated by Israeli paratroopers on June 7, 1967. That means that the 2,300th Passover in the count has to be the Passover in 1967, which occurred on the 25th of April. Were there exactly 2,300 Passovers between the Battle of Granicus in 334 bce and the liberation of Old Jerusalem and the Temple Mount during the Six-Day War in 1967?
Indeed!
By the way, I think we must have been typing our answers at the same time! Forgive me for repeating some of the information you provided--I didn't see your post when I entered the thread!
