Let me add something on your assertions.

This attitude of the Northem Kingdom, Israel, has an origin. Why did they stop walking in the ways of God?
When all Isra’el saw that the king Rechav‘am wasn’t listening to them, the people answered the king, saying: “Do we have any share in David? We have no heritage in the son of Yishai! Go to your tents, Isra’el! Care for your own house, David!” So Isra’el left for their tents. Since then Isra’el has been in rebellion against the dynasty of David to this day.
They had their sons and daughters pass through fire [as a sacrifice]. They used divination and magic spells. And they gave themselves over to do what was evil from Adonai’s perspective, thereby provoking him; so that Adonai, by now very angry with Isra’el, removed them from his sight. None was left except the tribe of Y’hudah alone.
Yes, Adonai came to despise all the descendants of Isra’el. He caused them trouble and handed them over to plunderers, until finally he threw them out of his sight. He tore Isra’el away from the house of David. They made Yarov‘am the son of N’vat king; and Yarov‘am drew Isra’el away from following Adonai and made them commit a great sin. The people of Isra’el followed the example of all the sins that Yarov‘am had committed and did not turn away from them, until Adonai removed Isra’el out of his sight, as he had said he would through all his servants the prophets. Thus Isra’el was carried away captive from their own land to Ashur, and it remains so to this day.
This fact explains the reason by which the people of Israel reject and rebelled against JESUS in his coming, for JESUS is of the David's house, JESUS is from the lineage of David. He came to his own homeland, yet his own people did not receive him. But to as many as did receive Him, to those who put their trust in His person and power, he gave the right to become children of God, not because of bloodline, physical impulse or human intention, but because of God. The Word became a human being and lived with us, and many saw his Sh’khinah, the Sh’khinah of the Father’s only Son, full of grace and truth.
Now, the Jews are waiting the manifestation of their messiah, they are not waiting JESUS in His second coming, they are focused in the manifestation of another man as their messiah, in truth will be an imposter. The Patriarch Jacob prophesied about this imposter, and it will be fulfiled in the days ahead. The false messiah of the Jews comes from the tribe of Dan. JESUS prophesyed about the coming and manifestation of this false messiah of the Jews.
JESUS prophesied about the manifestation of the false messiah after this return of the Jews to their land in 1948. He said to the Jews: John 5:43 - I am come in my Father's name, and ye receive me not: if another (AN IMPOSTER, UN USURPER, A FALSE MESSIAH) shall come in his own name, him ye will receive. This false messiah is the Beast which will rise up out of the earth as is written in Rev. 13:11to18. The Apostle Paul in his epistle to Thes. did write: (2Thes.2:9-12) 9 Even him, whose coming is after the working of Satan with all power and signs and lying wonders, 10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
11 And for this cause God shall send them strong delusion, that they should believe a lie: 12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
