The 3.5 years great tribulation of the anti-Christ / anti-Messiah, before Jesus Christ / Yeshua ha'Messiah returns to destroy non-believing earth, after rapturing believing earth, only enters this stage
after Israel is restored (Ezekiel 37 - 48), and the
temple is rebuilt in Ezekiel 40 (which the anti-Christ / anti-Messiah will enter and proclaim himself to be god to only be worshipped), also after the battle of Gog and Magog in Ezekiel 38. All this only happens after Ephraim (Israel's 10 tribes from the Gentiles), reunites with Judah (Israel's 3 tribes of the Jews) in Ezekiel 37, and Judah also then accepts Jesus Christ / Yeshua ha'Mashiach as heavenly King, under an earthly servant David (Judah). We are not yet at Ezekiel 37.
As father Jacob's / Israel's son Ephraim's 10 tribes, were scattered among the Gentiles 2700+ years following the Assyrian captivity, and had intermingled and adopted some Gentiles, and already came to accept Jesus / Yeshua, as the heavenly King of Israel, and can not make Aliyah to current Israel because of that, we await father Jacob's / Israel's son Judah's 3 tribes (Judah / Benjamin / Levi) to accept Jesus / Yeshua as the heavenly King of restored Israel. Then the two sticks of Ezekiel 37, of Ephraim and Judah will become one in the hand of heavenly Jesus the Christ / Yeshua ha'Mashiach, and Israel's restored covenant people will be whole again, under an earthly servant from the house of David (Judah). So before Ezekiel 40's temple, which the anti-Christ / anti-Messiah, will enter at the last 3.5 years of the end of days, after restored Israel, Judah's acceptance of Christ / Messiah and of their brother Ephraim (still among the Gentiles in the Body of Christ), of Ezekiel 37 will first happen.
Zechariah 12 (ESV)
10 "And I will pour out on the house of David and the inhabitants of Jerusalem a spirit of grace and pleas for mercy, so that, when they look on me, on him whom they have pierced, they shall mourn for him, as one mourns for an only child, and weep bitterly over him, as one weeps over a firstborn.
Romans 11 (ESV)
7 What then? Israel failed to obtain what it was seeking. The elect obtained it, but the rest were hardened,
8 as it is written, "God gave them a spirit of stupor, eyes that would not see and ears that would not hear, down to this very day."
9 And David says, "Let their table become a snare and a trap, a stumbling block and a retribution for them;
10 let their eyes be darkened so that they cannot see, and bend their backs forever."
11 So I ask, did they stumble in order that they might fall? By no means! Rather through their trespass salvation has come to the Gentiles, so as to make Israel jealous.
Ezekiel 37 (ESV)
18 And when your people say to you, 'Will you not tell us what you mean by these?'
19 say to them, Thus says the Lord God: Behold, I am about to take the stick of Joseph (that is in the hand of Ephraim) and the tribes of Israel associated with him. And I will join with it the stick of Judah, and make them one stick, that they may be one in my hand.
20 When the sticks on which you write are in your hand before their eyes,
21 then say to them, Thus says the Lord God: Behold, I will take the people of Israel from the nations among which they have gone, and will gather them from all around, and bring them to their own land.
22 And I will make them one nation in the land, on the mountains of Israel. And one king shall be king over them all, and they shall be no longer two nations, and no longer divided into two kingdoms.
23 They shall not defile themselves anymore with their idols and their detestable things, or with any of their transgressions. But I will save them from all the backslidings in which they have sinned, and will cleanse them; and they shall be my people, and I will be their God.
24 "My servant David shall be king over them, and they shall all have one shepherd. They shall walk in my rules and be careful to obey my statutes.
