Ezekiel 37(CJB) "Make them Y'hudah&Efrayim a Single Stick", How to Realize?

Ezekiel 37(CJB)​

15 The word of ADONAI came to me:
16 "You, human being, take one stick and write on it, 'For Y'hudah and those joined with him [among] the people of Isra'el.' Next, take another stick and write on it, 'For Yosef, the stick of Efrayim, and all the house of Isra'el who are joined with him.'
17 Finally, bring them together into a single stick, so that they become one in your hand.
18 When your people ask you what all this means,
19 tell them that Adonai ELOHIM says this: 'I will take the stick of Yosef, which is in the hand of Efrayim, together with the tribes of Isra'el who are joined with him, and put them together with the stick of Y'hudah and make them a single stick, so that they become one in my hand.'
20 The sticks on which you write are to be in your hand as they watch.
21 Then say to them that Adonai ELOHIM says: 'I will take the people of Isra'el from among the nations where they have gone and gather them from every side and bring them back to their own land.
22 I will make them one nation in the land, on the mountains of Isra'el; and one king will be king for all of them. They will no longer be two nations, and they will never again be divided into two kingdoms.
23 "'They will never again defile themselves with their idols, their detestable things, or any of their transgressions; but I will save them from all the places where they have been living and sinning; and I will cleanse them, so that they will be my people, and I will be their God.
24 My servant David will be king over them, and all of them will have one shepherd; they will live by my rulings and keep and observe my regulations.
25 They will live in the land I gave to Ya'akov my servant, where your ancestors lived; they will live there - they, their children, and their grandchildren, forever; and David my servant will be their leader forever.
26 I will make a covenant of peace with them, an everlasting covenant. I will give to them, increase their numbers, and set my sanctuary among them forever.
27 My home will be with them; I will be their God, and they will be my people.
28 The nations will know that I am ADONAI, who sets Isra'el apart as holy, when my sanctuary is with them forever.'"
