What is this serpent of brass that Yahweh told Moses to make?
Num 21: v5. And the people spake against Yahweh, and against Moses, wherefore have ye brought us up out of Egypt to die in the wilderness? For [there is] no bread, neither [is there any] water; and our soul loatheth this light bread.
V6. And Yahweh sent fiery serpents among the people, and they bit the people; and much people of Israel died.
V7. Therefore, the people came to Moses, and said, We have sinned, for we have spoken against Yahweh, and against thee; pray unto Yahweh, that he take away the serpents from us. And Moses prayed for the people.
V8. And Yahweh said unto Moses, Make thee a fiery serpent, and set it upon a pole (notice our Creator said put it up on a pole, not a cross, poles are vertical unlike a cross): and it shall come to pass, that every one that is bitten, when he looketh upon it, shall live.
V9. And Moses made a serpent of brass, and put it upon a pole (vertical beam not a horizontal beam, not a cross), and it came to pass, that if a serpent had bitten any man, when he beheld the serpent of brass, he lived.
The chief Angel Lucifer fell away (Father and Son foresaw this, it was part of the Father's plan and took a third of the angels with him and now is Satan ). He received permission to test Eve in the garden of the field which Yahweh had made. Gen 3: v1. And he said unto the woman, Yea, hath Yahweh said, Ye shall not eat of every tree of the garden.
V2. And the woman said unto the serpent, We may eat of the fruit of the trees of the garden:
V3. But of the fruit of the tree which [is] in the midst of the garden, Yahweh hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die.
V5. For Yahweh doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
V4. And the serpent said unto the woman, Ye shall not surely die (yet):
V6. And when the woman saw that the tree [was] good for food, and that it [was] pleasant to the eyes, and a tree to be desired to make [one] wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat.
V7. And the eyes of them both were opened, and they knew that they [were] naked (ashamed/sin); and they sewed fig leaves together, and made themselves aprons.
What is this tree of the knowledge of good and evil?
Gen 2: v16. And Yahweh commanded the man, saying, of every tree of the garden thou mayest freely eat.
V17. But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day (within a thousand years) that thou eatest thereof thou shalt surely die.
V24. Therefore, shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh (one body like Messiah and assembly are one body/one purpose).
V25. And they were both naked, the man and his wife, and were not ashamed (without sin).
The tree of the knowledge of good and evil is none other than the fallen angel Satan. He was once the sum total of perfection and knew good until sin (evil) was found in him.
Ezk 28: V3. Behold, thou [art] wiser than Daniel; there is no secret that they can hide from thee:
V6. Therefore, thus saith Yahweh; Because thou hast set thine heart as the heart of Yahweh;
V9. Wilt thou yet say before him that slayeth thee, I [am] Yahweh? But thou [shalt be] a man (created being like man), and no Yahweh, in the hand of him that slayeth thee.
V12. Son of man, take up a lamentation upon the king of Tyrus (symbolic of Satan, Tyrus is controlled by Satan), and say unto him, Thus saith Yahweh; Thou sealest up the sum, full of wisdom, and perfect in beauty (Lucifer the archangel or Chief Angel was beautiful, unlike our Creator and the two witnesses, Lucifer now replaced by Michael and Gabriel).
V13. Thou hast been in Eden the garden of Yahweh (was with Yahweh in the garden probably when he created the garden of Eden before Adam was even created); every precious stone [was] thy covering, the sardius, topaz, and the diamond, the beryl, the onyx, and the jasper, the sapphire, the emerald, and the carbuncle, and gold: the workmanship of thy tabrets and of thy pipes was prepared in thee in the day that thou wast created.
V14. Thou [art] the anointed cherub (Head Angel) that covereth; and I have set thee [so:] thou wast upon the holy mountain of Yahweh; thou hast walked up and down in the midst of the stones of fire.
V15. Thou [wast] perfect in thy ways from the day that thou wast created, till iniquity was found in thee (part of the Father's plan).
V16. By the multitude of thy merchandise they have filled the midst of thee with violence, and thou hast sinned: therefore I will cast thee as profane out of the mountain of Yahweh: and I will destroy thee, O covering cherub, from the midst of the stones of fire.
V17. Thine heart was lifted up because of thy beauty, thou hast corrupted thy wisdom by reason of thy brightness: I will cast thee to the ground, I will lay thee before kings, that they may behold thee.
V18. Thou hast defiled thy sanctuaries by the multitude of thine iniquities, by the iniquity of thy traffick; therefore will I bring forth a fire from the midst of thee (Our Creator likely takes the hedge down about Satan and the fallen Angels and a lake of fire consumes their spiritual bodies; see article Wrath of YahwehShua), it shall devour thee, and I will bring thee to ashes upon the earth in the sight of all them that behold thee.
Isaiah and John in Revelation confirm the fall of Lucifer and the fact that he took a third of the angels with him (spiritual bodies must be a lot stronger than flesh bodies because he could only deceive a third of the angels, however, he deceives all in this world the darkness below).
Isa 14: v12. How art thou fallen from heaven, O Lucifer, son of the morning! [how] art thou cut down to the ground, which didst weaken the nations
V13. For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of Yahweh: I will sit also upon the mount of the congregation, in the sides of the north:
V14. I will ascend above the heights of the clouds; I will be like the most High.
V15. Yet thou shalt be brought down to hell, to the sides of the pit.
Rev 12: v3. And there appeared another wonder in heaven; and behold a great red dragon (Satan), having seven heads and ten horns, and seven crowns upon his heads.
V4. And his tail drew the third part of the stars (angels) of heaven, and did cast them to the earth: and the dragon stood before the woman which was ready to be delivered, for to devour her child as soon as it was born.
V5. And she brought forth a man child (Messiah), who was to rule all nations with a rod of iron: and her child was caught up unto Yahweh the Father (after his resurrection he ascended up to the Father as YahwehShua, the perfect wave sheaf offering), and [to] his throne.
V6. And the woman (much of the assembly will be taken to a place of safety in the last 3 and 1/2 years leading up to the 7th Trump) fled into the wilderness, where she hath a place prepared by YahwehShua, that they should feed her there a thousand two hundred [and] threescore days (3 and 1/2 years of 30-day months leading up to the return of YahwehShua at the 7th trumpet).
Full circle back to the serpent of brass and what it could mean spiritually? Messiah gives us the clue:
Jhn 3: v14. And as Moses lifted up the serpent in the wilderness, even so must the Son of man (Messiah) be lifted up (on a vertical pole not a cross or horizontal beam):
V15. That whosoever believeth in him should not perish, but have eternal life (in the kingdom eternally, the rest of creation outside the kingdom with eternal life).
The people with Moses were cured when they looked upon this serpent of brass. But the serpent represents the devil or sin being lifted up on a beam! Messiah was lifted up on a beam into a tree, is he a devil? Yahweh forbid! What do the scriptures say?
Gal 3: v13. Messiah redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed [is] every one that hangeth on a tree:
Jhn 1: v29. The next day John seeth Messiah coming unto him, and saith, Behold the Lamb of Father Yahweh, which taketh away the sin of the world (all sin /past /present/ future).
Our Creator is the only person to die in sin and the only sin sponge which has wiped away all sin (past, present, and future) to give life to all including all the fallen angels and all humans who fail to overcome. Like the serpent lifted up in the wilderness, our Creator was lifted up on a vertical beam or pole into a tree. That single greatest act of love of all time destroys death for all creation in the seen and unseen world.
Heb 2: v14. Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil;
HalleluYahwehShua!
