In Ezekiel the Prophet we read God saying: "I save my flock, and they shall no more be a prey; and I will judge between cattle and cattle. And I will set up one shepherd over them, and he shall feed them, even my servant David; he shall feed them, and he shall be their shepherd. And I the LORD will be their God, and my servant David a prince among them; I the LORD have spoken it. And I will make with them a covenant of peace, and will cause the evil beasts to cease out of the land: and they shall dwell safely in the wilderness, and sleep in the woods. And I will make them and the places round about my hill a blessing; and I will cause the shower to come down in his season; there shall be showers of blessing. (Ezekiel 34:22/26)
Gentile believers in the churches of America will not want to accept the truth when they hear Israel will become as it were the Queen of the nations, and Gentile believers will go to Israel to worship the Lord in submission to the Israelites.
In a similar series of verses as you just read above, Ezekiel quotes the LORD God as saying: "And the heathen shall know that I the LORD do sanctify Israel, when my sanctuary shall be in the midst of them for evermore." (Ezekiel 37:28) The LORD is not going to center his power in Washington D.C. or in Rome anymore. Jesus will rebuild the temple for the Thousand Year Reign immediately upon his arrival to set up his global Kingdom.
The heathen refers to Gentile believers worldwide Resurrected and returned to their own lands to serve the Lord there and to go to Jerusalem regularly to worship Jesus.
Isaiah the Prophet speaking for God tells the Jewish people, "Incline your ear, and come unto me: hear, and your soul shall live; and I will make an everlasting covenant with you, even the sure mercies of David. Behold, I have given him for a witness to the people, a leader and commander to the people. Behold, you shall call a nation that thou know not, and nations that knew not thee shall run unto you because of the LORD your God, and for the Holy One of Israel; for he has glorified you." (Isaiah 55:3/5)
In a similar forecast to Israel, Jeremiah the Prophet writes for God saying: "For I am with you, saith the LORD, to save you: though I make a full end of all nations whither I have scattered you, yet will I not make a full end of you: but I will correct you in measure, and will not leave you altogether unpunished." (Jeremiah 30:11)
So every nation where Jewish people presently reside in the Disapora will no longer exist as nations. America will no longer exist as a nation. Germany will no longer exist as a nation. Russia will no longer exist as a nation. But Israel will regain its State upon the return of Christ even though they will no longer be a democracy ruled by voters.
We will all live in a global theocracy ruled over for a thousand years by Christ and Israel will be as it were the Queen of the nations. All of the holy Prophets and Apostles will be there in the First Resurrection participating in this future theocracy with David as King over Israel, while Jesus reigns as King of kings and Lord of lords over the entire earth.
David knew he was chosen to rule as king over Israel forever when he was first made king. We find David saying to Israel in 1 Chronicles 28:4: "the LORD God of Israel chose me before all the house of my father to be king over Israel forever: for he has chosen Judah to be the ruler; and of the house of Judah, the house of my father; and among the sons of my father he liked me to make me king over all Israel:"
Isaiah the Prophet spoke of Jesus sitting upon the throne of David to rule the world saying, "Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even forever. The zeal of the LORD of hosts will perform this." (Isaiah 9:7)
The angel told Mary, "And, you shall conceive in your womb, and bring forth a son, and shall call his name JESUS. He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David: And he shall reign over the house of Jacob forever; and of his kingdom there shall be no end. (Saint Luke 1:31/33)
In all of this we are speaking of the kings of the Dynasty of David sitting on the throne of David as well as Jesus, the one to rule over Israel and the Lord to rule over the entire global Kingdom.
Here is Solomon's prayer to confirm that thought to your mind.
Now therefore, O LORD God of Israel, keep with thy servant David my father that which
thou hast promised him, saying, There shall not fail thee a man in my sight to sit upon
the throne of Israel; yet so that thy children take heed to their way to walk in my law,
as thou hast walked before me. (2 Chronicles 6:16)
Eliakim will "be a father to the inhabitantss of Jerusalem, and to the house of Judah," Isaiah 22:20/22 The key to the house of David will be on his shoulders.
If anyone in the worldwide global Kingdom Christ sets up for a thousand years,
wishes to gain access to the throne room of the royal house of David, they will
have to go through Eliakim; whether it be Christ or King David or any of the
dyanasty of David.
