Understanding the Firstfruits

In Leviticus chapter 23 we can read the Levitical practice of the firstfruit services the high priest was to perform yearly, (I have put a link at the bottom of this page to read what ALFRED EDERSHEIM has written about the wave loaves) we can read in Leviticus:23 that there are two loaves of bread baked with yeast, and they are the "wave loaves" and they are the firstfruits unto the Lord.
We can read in Revelations that GOD has 144,000 men from the tribes of Israel that have been redeemed from the earth, and they are virgins, they follow the lamb withersoever he goeth. They are without fault before the throne of GOD. They are the firstfruits unto GOD and to the Lamb.

Now with that being said and understood, I will add that "GOD is not the author of confusion", the two loaves of bread that are baked with leaven(sin),and waved by the high priest yearly before the Lord, they represent two separate groups of men from the tribes of Israel that are chosen of GOD perfect in their generations and they are a type/shadow of the firstfruits of GOD's harvest of the earth.

Two Separate Wave Loaves

In the services performed by the High Priest to present and wave the two loaves of bread before GOD are wonderfully amazing.
The preparation of the flour to bake the two wave loaves of bread (as described in Alfred Edersheim's commentaries on the wave loaves) is recorded as being sifted through twelve sieves to produce the "Fine Flour" GOD required in Lev 23:17 and this reflects the blameless obedient morals described of the firstfruits in Rev 14:4, additionally these two loaves of bread are required of GOD to be baked with leaven,(yeast) and we know that leaven,(yeast) is a synonym for Sin, and this reflects the sinful nature of Man.

Now the actual service performed by the High Priest in waving these two loaves before GOD is just simply amazing.
The High Priest would take two separate lambs without blemish and wave these before GOD while still alive, then the two lambs would be sacrificed upon the alter, and the choice parts of the meat (breast and shoulder) would then be waved together with the two firstfruit wave loaves.
This could only be done by the priest holding a portion of lamb in one hand while holding one of the wave loaves in the other hand, and then waving them both before GOD, to the north, the south, the east, the west, and this process was repeated until all of the lamb had been waved with the two separate firstfruit loaves of bread.

So, what GOD is demonstrating to us in the Law of harvest of firstfruits should be clear, every year the Priest would take two separate loaves of bread made with leaven that represents the "conceived in sin" nature of man, they are "the firstfruits" he would then wave these before GOD with two separate sinless lambs, one for each loaf of bread. That should be clear to see, then we go to revelation14:4 and GOD is telling us these two loaves of bread are actually chosen men of Israel.
but wait...there are two loaves of bread!... does this indicate two separate groupes of men "firstfruits" that GOD is harvesting before the feast of ingathering at the end of the year?

The Graves were Opened

And the graves were opened; and many bodies of the saints which slept arose, And came out of the graves after his resurrection, and went into the holy city, and appeared unto many.

This my friends was a resurrection event, and according to the Law of harvest this can only be one of the loaves of firstfruits, this can only mean that GOD is taking a firstfruit harvest from both covenants.
This explains the two lambs sacrificed and waved with the bread of firstfruits, a lamb for each covenant representing Christ to come as the lamb in the Law, and Christ in the Law of grace
