Revelation 3:9 9 Behold, I will make them of the synagogue of Satan, which say they are Jews, and are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee.
Isaiah 7:14. A virgin shall conceive. They ignore these chapters and still hold to traditions.Zionism.Isaiah was written to the House of Israel. Jeremiah was written to Judah"jews". There are two seperate houses
Isaiah 53 is not about Jesus ,nor it's about Israel. Both rabbinical and christian interpretations are wrong. It's about the tribe of Levite personified in their forefather Levi as a righteous servant of the Lord. "He had no beauty no majesty", that's not about Jesus it's about the tribe of Levites coming out of the desert like a dry shoot ,nothing special about them ,and yet Lord chose them to the be priesthood also a sacrifice for Israel. That's why it says that he should see his offspring, in other words the tribe of Levites will be back again to their glory. In numbers we see the tribe of levites were chosen to be a sacrifice for every first born of Israel .Of course it wasn't a human sacrifice, but the Lord would bring judgment on them when Israel backslided. Also Levites were persecuted by their people after their turned to foreign gods. That's why it says he was despised and rejected, because the tribe of Levites were pushed out by Jeroboam from the rest of the tribes when Israel was devided. And they became despised and hated, because they didn't even receive inheritance, so they became wanderers, rejected. But they didn't understand that this was God's way of sacrificing Levites fo the sake of Israel. That's why it says " Yet who of his generation protested?". In other words nobody from Levites protested they accepted their fate
Isaiah 53 says very clearly the suffering servant is the Jewish people. The Jewish Hebrew Bible ends with Chronicles II. Cyrus has defeated the Babylonians and Jews are welcome to return to their homeland. Prophecy fulfilled.
It’s not a mystery at all. You are reading Isaiah backwards starting with the idea that Jesus fulfills the prophecy in Isaiah. If you read it without biases or prejudgments it’s not there. If yo it read it with an understanding of what was happening in Judah and Israel at the time Isaiah was writing the meaning is obvious but of course you know nothing about the time periods Isaiah was written.
