Of course, the feast days of YAHUAH are critically important to our understanding of prophecy.  Let me go so far to say that when it comes to understanding the words of the prophets, I do not believe it possible to fully comprehend these writings without adherence to the Torah of YAH, which includes the keeping of Shabbath and the keeping of the moediym – the feasts of YAH.  See Vayiqra 23 for one such roster of these moediym.  Allow a brief summary:

Beyond the Sabbath of the seventh day, is of course the Sabbath of the seventh year (the Sabbatical or Shemitah year), and after seven sevens of years, comes the Jubilee on the fiftieth year. 

In addition to the regular Sabbath, there are three high Sabbaths points (chag), which are Matsah (the feast of unleavened bread); Sheva’oth (the day of seven sevens, fifty days beyond the Sabbath within Matsah), and Sukka’oth (the feast of tabernacles).  Yom Teruah (also known as Rosh Hashanah) and Yom Kippur are also Sabbaths, as is Bikkoor (First Fruits). 

So, the feasts (moediym) are Pecach (Passover), Matsah (Unleavened bread), Bikkoor (First Fruits) (sometimes called the Latter Rain); Sheva’oth (the feast of sevens, or Pentecost) (the Shamash, if you will); and Yom Teruah (Trumpets), Yom Kippur (Atonement), and Sukka’oth (Tabernacles) with its finale Simcha Torah (the Joy of the Torah) (sometimes called the Former Rain).

Immediately, we begin to see how such understanding reveals prophecy:

Devariym (Deuteronomy) 11:14

That I will give you the rain of your land in his due season, the first rain (yoreh) and the latter rain (malqosh), that you may gather in your corn, and your wine, and your oil.

We see that the rains are markers that ultimately result in a harvest.  Similarly, we can consider that prophetically, YAH will reap his own harvest in accord with the yoreh and the malqosh. 

Yermiyahu (Jeremiah) 5:24

Neither do they say in their heart, Let us now fear YAHUAH ELOHAYNU that gives rain, both the former (yoreh) and the latter (malqosh), in his season: he reserves unto us the appointed weeks (shevua) of the harvest.

Here in this passage we see this word shevua appear.  We have discussed this word at length in regard to the famous passage in Daniye’l 9:24.  In its micro application, this word is tasken to means weeks, yet it could also mean a group of seven years, and even a group of sevens of years reaching Jubilee. If shevua is construed to mean the sevens which reach Jubilee, then we see that he reserves unto us the appointed Jubilees of the harvest. Such a statement would corroborate the idea that man’s days are one hundred twenty Jubilee years, or six thousand years before the reign of Mashiach.   

Husha (Hosea) 6:3

Then shall we know (yada), if we follow on to know (yada) YAHUAH: his going forth is prepared as the morning; and he shall come unto us as the rain, as the latter (malqosh) and former rain (yoreh) unto the earth (eretz).

Where the word yada is concerned, it means both to praise, and to know.  To know him is to praise him, and to praise him is to know him.

Although we have a bit of a struggle in understanding that the latter rain is in the spring, and the former rain is in the fall, consider the words of Yo’el:

Yo’el (Joel) 2:23

Be glad then, ye children of Zion, and rejoice in the YAHUAH your ELOHAYCHA: for he hath given (natan) you the former rain (ma’yoreh) moderately, and he will cause to come down for you the rain, the former rain (ma’yoreh), and the latter rain (malqosh) in the first (rishon) month.

We see here, that the latter rain takes place in the first month, or the month of Aviv, which is in the spring.

Ya’akov (James) 5:7

Be patient therefore, brethren, unto the coming of ADONAI. Behold, the husbandman waits for the precious fruit of the earth, and has long patience for it, until he receive the early and latter rain.

These prophecies center around the moediym of YAHUAH (the feasts), yet they also predict the second advent of YAHUSHA HAMASHIACH.

Now that we understand these options, we have four blood moons to discuss:

     First new moon:          Adom yare’ach rishon, (latter rain).

     Second new moon:     Adom yare’ach sheniy, (former rain).

     Third new moon:        Adom yare’ach shelishiy, (latter rain).

     Fourth new moon:      Adom yare’ach reviy’iy, (former rain).
