This is Just a Passover Lie
As Pascha (Passover) is approaching, the Jews are still blind as to what the Lamb symbolises. The lamb for Pascha was/is symbol of the death of the Messiah, our Moshiach or Saviour, and our Redeemer, but the Jewish Orthodoxy still regard the killing and eating of the lamb as an act of defiance to the Egyptians who regarded the ram as their deity—the Ram-god Khnum—the Lord of the First Cataract in Upper Egypt, believed to preside over the annual rise of the Nile.

In fact, the calves, oxen or even the lamb (the Targum says “because we shall take sheep, which are the abomination of the Mizraee”) weren’t much of a deity of the Egyptians where both the children of Israel and the Pharaohs lived, but an abomination, not a deity, of these Egyptians in lower Egypt, Exodus 8:26.
Second, the ancient Egyptians had more prominent gods and goddesses like Osiris, Isis and Horus but no defiance were ruled against them? Why? Why only a little known deity of Upper Egypt (near the city of Aswan) which the children of Israel would have little contact with since they lived in Goshen of lower Egypt? Also, the Pharaohs and their princes lived in Zoan, known as “the royal city of the Pharaohs” – a city of Lower Egypt.
The Scriptures nowhere say that the sacrifice of the lamb was a defiance of this pagan god, but to reject the Moshiach, they planted “a seed of falsehood (Isaiah 57:4)” and they developed further as a figment of Jewish imagination over time.
In fact, the blood of the Paschal lamb was to foreshadow the atonement of the blood of Yeshua at Calvary, but first, the blood of the lamb which was placed on the doorposts was to save the children of Israel in Egypt from death. And later apostle John identified Yeshua as the lamb when he came for baptism, for John exclaimed, “Behold the Lamb of God!” (John 1:36) And under inspiration Nathanael identified him further and said, “Rabbi, Thou art the Son of God; Thou art the King of Israel,” (verse 49)
In the Targum version of Isaiah 52:13 it identifies “my Servant the Messiah” whom rabbinical Judaism says is Jacob or Israel. In Isaiah 53:7 it says, “He was oppressed, and He was afflicted, yet He opened not his mouth; He is brought as a lamb to the slaughter; and as a sheep before her shearers is dumb, so He openeth not His mouth.” Of course, this clearly point to Yeshua, “my Servant the Messiah” that is, the slaughtered lamb was the Son of God, the Christ, the rejected Moshiach by the Orthodoxy.
Isaiah further says they lie, “O house of Jacob, which are called by the name of Israel . . who swear by the name of the Lord and make mention of the God of Israel, but not in truth!” Isaiah 48:1. “Not in truth” means falsehood or a lie.
Further, the Orthodoxy are not just denying who the suffering servant the Scripture is writing about, but purposely choose to be blind, groping around as if they have no eyes: “We grope for the wall like the blind, and we grope as if we had no eyes,” Isaiah 59:10.
The Targum was started by Ezra for those returning from the Babylonian exile, and for these returnees, they could only understand the Scriptures in Aramaic. Hence the Targum is as if the second Moses, Ezra, is speaking to them in ancient times and to us from the Hebrew Sacred Text.
They have to be thrown into captivity to get rid of idolatries, falsehood and other wickedness; do they have to go into captivity again to know this vital truth? For more, see Ezekiel 4 – 390/40 Years and the Sword from the South in Ezekiel 20:45 to 21:5?
