The clearest prophetic text over its duration is that of Zechariah and the Book of Revelation, both of which describe the Day of Jehovah as one day, or the
only date of one day:
"And it will become one day that is known as belonging to Jehovah. It will not be day, nor will it be night; and at evening time there will be light" (Zechariah
This text alone shows that it is a 24-hour day, and not a period of few days, because it is written that at the time of day, it will be neither day nor night, and that at the
time of evening there will be light. However, the most explicit text is that of the book of Revelation, where this Day is connected with a date on the Jewish calendar. In Revelation 11:18, it is written: "But the nations became wrathful, and your own wrath
came, and the appointed time came for the dead to be judged and to reward your slaves the prophets and the holy ones and those fearing your name, the small and the great, and to bring to ruin those ruining the earth" (Revelation 11:18). This text refers to
the time of the Great Tribulation, when God "will bring ruin to those who ruin the earth". However, what is even more interesting, is that verse 19 repeats this time in enigmatic way, connecting the Day of Jehovah withe the vision of the ark of his covenant:
"And the temple sanctuary of God in heaven was opened, and the ark of his covenant was seen in his temple sanctuary. And there were flashes of lightning and voices and thunders and an earthquake and a great hail" (Revelation 11:19).
This verse has two main parts: The first is the vision of the "ark of his covenant", the date of only one day. Indeed, Jehovah God did not allow to see the ark of his covenant (by the high priest), any day other than
Ethanim (Tishri), 10 (Leviticus 16:2,29). The second part of the verse 19, is the symbolic description of the Great Tribulation. The Ethanim, 10 (Tishri), corresponds to the dramatic celebration of the Day of Atonement. The process of celebration is described
in Leviticus chapter 16. It is a dramatic moment, because it describes symbolically, what will happen during the Day of Jehovah, the Great Tribulation. It will be a day of sadness, because Jehovah had given this instruction regarding this day: "It is a sabbath
of complete rest for you, and you should afflict yourselves. It is a lasting statute" (Leviticus 16:31) (REALITY OF THE
THE GREAT TRIBULATION WILL TAKE PLACE IN TISHRI 10TH
the vision of the "ark of his covenant", the date of only one day. Indeed, Jehovah God did not allow to see the ark of his covenant (by the high priest), any day other than Ethanim (Tishri), 10
“And the temple sanctuary of God in heaven was opened, and the ark of his covenant was seen in his temple sanctuary. And there were flashes of lightning and voices and thunders and an earthquake
and a great hail”
This famous date of Tishri 10th appears in
the Bible, several times, in an encrypted or symbolic way, in direct and indirect relationship with the prophetic descriptions of the Great Tribulation (The month of Tishri is the seventh month of the Hebrew lunisolar calendar, between the months of September/October)
(Names of months of the Hebrew Calendar):
“In the 25th year of our exile, at the beginning
of the year, on the tenth day of the month, (…) By means of visions from God, he brought me to the land of Israel and set me down on a very high mountain, on which there was a structure like a city to the south” (Ezekiel 40:1a,2): The
prophet Ezekiel has a vision of the earthly administration of the Kingdom of God, after the 7 months of purification
immediately following the Great Tribulation, Nisan 10th (Ezekiel 39: 12-16 ; 40:1a “at the beginning of the year (Nisan),
on the tenth day (10th) of the month”). If we add the intercalary month Veadar, in accordance with metonic cycle, we have exactly the date of TISHRI 10th. The prophetic information about the 7 months, in Ezekiel 39: 12-16 shows that the Great Tribulation will happen in a lunisolar year of 13 months.
not be afraid of the things you are about to suffer. Look! The Devil will keep on throwing some of you into prison so that you may be fully put to the test, and you will have tribulation for ten days. Prove yourself faithful even to death,
and I will give you the crown of life” (Revelation 2:10): The mention of the symbolical 10 days of tribulation, after which the disciples of Christ have their reward of everlasting life, seems to evoke the 10 days of Tishri, mentioned later in Revelation
11:19 (Numbers in the Bible). In Tishri 10th, all of the 144,000 and the Great Crowd
will be permanently sealed for everlasting life, in the Heavens for the group of 144000, and on Earth for the Great Crowd (Revelation 7).
“It will happen in summer and in winter” (Zechariah 14:8b)
This important biblical information indicates that this day of the Ethanim, 10 (Tishri) (month of the biblical calendar), corresponding with the day of the great tribulation,
will be the passage from the summer solstice to the autumn equinox (beginning of winter in the Bible), that is to say a September, 22, after the sunset (summer) and at the same time, the day of September, 23 (autumn "winter") (solar calendar).
“In that day there will be no precious light—things will be congealed. And it will become one day that is known as belonging to Jehovah. It will not be day, nor will it be night;
and at evening time there will be light. In that day living waters will flow out from Jerusalem, half of them toward the eastern sea and half of them toward the western sea. It will happen in summer and in winter. And Jehovah will be King over all the earth.
In that day Jehovah will be one, and his name one” (Zechariah 14:6-9).
"It will happen in summer and in winter" is a precious and very accurate indication of when the
"Great Jehovah Day", the Great Tribulation, will take place. First of all it is necessary to specify the meaning of the word "winter" in this prophecy. According the Strong's Concordance (H2779), the transliteration of the Hebrew word "chôreph" (H2779)
translated “winter” in this text, in biblical usage, means: properly, the crop gathered, that means (by implication) the autumn (and winter) season; figuratively, ripeness of age. So, in this text, the word “winter” means “autumn”,
that is, the beginning of winter.
This prophecy gives extraordinary information, if we cross it with the information of Revelation 11:19 which Indicates that the Great Tribulation will
take place on Tishri 10th: "And the temple sanctuary of God in heaven was opened, and the ark of his covenant was seen in his temple sanctuary. And there were flashes of lightning and voices and thunders and an earthquake and a great hail". This text is the
narrative, in one sentence, of the Great Tribulation, the second part of verse 19: "And there were flashes of lightning and voices and thunders and an earthquake and a great hail".
the first part mentions that the “ark of his covenant” was visible. But God did not allow the high priest to see the “ark of his covenant” any time in the sanctuary temple, but only on Tishri 10th (Leviticus 16: 2). The mention
of the vision of the “ark of his covenant” is obviously extraordinary information from the day of the great tribulation: it will take place a Tishri 10th. However, Zechariah 14:8 indicates that this same day, the Day of Jehovah, the
Great Tribulation, which will take place on Tishri 10th, will be the passage from summer to autumn (as beginning of winter). This second extraordinary information indicates that the Tishri 10th of the Hebrew Bible Calendar will correspond
to a 22 (after the sunset in Jerusalem) and September 23rd, of the Gregorian calendar, the time of passage between summer and autumn (beginning of the winter).
Thus, to know
the precise year, it would be enough to compare the Gregorian calendar and the current Hebrew calendar to see what year would correspond to Tishri 10th (Yom Kippur) with the precise date of the transition from summer to autumn equinox, namely, September 22nd
and 23rd. But it's not so simple. By making a quick search of the dates corresponding to Tishri 10th, the date of the celebration of the Hebrew Yom Kippur, from the year 2019 to at least the year 2026, no date corresponds between the Hebrew calendar (lunisolar)
and the Gregorian calendar (solar). However, it exists! Yes, it exists by employing, the biblical method of adjustment between, the current Hebrew calendar and the biblical calendar by strictly taking into account the lunar cycle mentioned in Psalms 81:3.
This demonstration will be made in a future page of study entitled "The Day of Jehovah", where will appear the correspondence between the future "Tishri 10th" with the same day, September 22 and 23, the passage of the summer to the equinox of autumn... And
it is moreover a lunisolar year... The year 2023 corresponds perfectly to
the two criteria, 10 Tishri and the passage to the autumnal equinox.
