SUSAN:
 
If Eddie Chumney http://www.hebroots.com/chap7.html  is correct the Ratpure
must occur when the LAST Trumpet blasts.
 
If he is correct this event takes place on Rosh HaShanah.
 
While on Yom Kippur the GREAT Trumpet is heard.
 
........
In Judaism, there are three trumpets (shofarim) that have a name.
 
They are the first trump, the last trump, and the great trump.
 
Each one of these trumpets indicates a specific day in the Jewish year.
 
The first trump is blown on the Feast of Shavuot (Pentecost) (Exodus [Shemot]
19:19). It proclaimed that G-d had betrothed Himself to Israel.
 
The last trump is synonymous with Rosh HaShanah, according to Theodore
Gaster in his book, Festivals of the Jewish Year, in his chapter on
Rosh HaShanah. Herman Kieval also states the same thing in his book,
The High Holy Days (Volume I, Rosh HaShanah, Chapter 5, Footnote 11),
in the chapter on the shofar.
 
The great trumpet is blown on Yom Kippur, which will herald the return of
the Messiah Yeshua back to earth (Matthew [Mattityahu] 24:31).
 
The first and last trump relate to the two horns of the ram, which according to
Jewish tradition, was caught in the thicket on Mount Moriah when Abraham
was ready to slay Isaac (Yitzchak) and offer him up as a burnt offering (olah).

In Pirkei Avot (the sayings of the fathers), Rabbi Eliezer
tells us that the left horn (first trump) was blown on Mount Sinai,
and its right horn (the last trump) will be blown to herald the coming
of the Messiah.
 
Isaiah (Yeshayahu) 18:3 and First Thessalonians 4:13-18 speak of
the resurrection of the dead. First Thessalonians
chapter 5 continues with the day of the L-rd and the birthpangs of the
Messiah. First Thessalonians 4:16-17 says that the dead in Messiah
will rise first, and that the catching away of the believers will
immediately follow.
 
Psalm (Tehillim) 27:5 says the righteous will be hid in the time of trouble.
This psalm is read every day during the 40-day period of Teshuvah.
 
Second Thessalonians 2:1 says, "Now we beseech you, brethren, by
 the coming of our Lord Jesus Christ, and by our gathering together unto Him."
 
The phrase, "gathering together" comes from the Greek word episunagoge,
which means "an assembly." In Numbers (Bamidbar) 10:2-3, the trumpet is blown to
assemble the people. The blowing of the trumpet and the assembling of
the people also appear together in First Thessalonians 4:16-17 and
First Corinthians 15:51-53.
