“It will happen in summer and in winter”
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...
