As far as #5… I usually find scripture rarely introduces an idea or prophecy in only one place. So if there is an actual covenant made with the AC that results in Israel’s invasion and exile, then we should have other places in scripture that talk about this or foreshadow it. I believe this was foreshadowed as early as the exodus when they were taking the promised land. And I believe there are many other allusions to it in later prophetic books and psalms. Here’s several passages to ponder….
“And I will set your border from the Red Sea to the Sea of the Philistines, and from the wilderness to the Euphrates, for I will give the inhabitants of the land into your hand, and you shall drive them out before you. You shall make no covenant with them and their gods.”
Exodus 23:31-32 ESV (notice the borders they are supposed to possess, this hasn’t been fulfilled yet).
“Because you have said, “We have made a covenant with death, and with Sheol we have an agreement, when the overwhelming whip passes through it will not come to us, for we have made lies our refuge, and in falsehood we have taken shelter”;”
Isaiah 28:15 ESV
“Then your covenant with death will be annulled, and your agreement with Sheol will not stand; when the overwhelming scourge passes through, you will be beaten down by it. As often as it passes through it will take you; for morning by morning it will pass through, by day and by night; and it will be sheer terror to understand the message.”
Isaiah 28:18-19 ESV. (Describes the invasion of Judea when covenant is broken)
“They say, “Come, let us wipe them out as a nation; let the name of Israel be remembered no more!” For they conspire with one accord; against you they make a covenant— the tents of Edom and the Ishmaelites, Moab and the Hagrites, Gebal and Ammon and Amalek, Philistia with the inhabitants of Tyre; Asshur also has joined them; they are the strong arm of the children of Lot. Selah”
Psalm 83:4-8 ESV. (These are all the peoples/nations in those boundaries laid out in exodus).
“Day and night they go around it on its walls, and iniquity and trouble are within it; ruin is in its midst; oppression and fraud do not depart from its marketplace. For it is not an enemy who taunts me— then I could bear it; it is not an adversary who deals insolently with me— then I could hide from him. But it is you, a man, my equal, my companion, my familiar friend. We used to take sweet counsel together; within God’s house we walked in the throng. My companion stretched out his hand against his friends; he violated his covenant. His speech was smooth as butter, yet war was in his heart; his words were softer than oil, yet they were drawn swords.”
Psalm 55:10-14, 20-21 ESV
“Can wicked rulers be allied with you, those who frame injustice by statute? They band together against the life of the righteous and condemn the innocent to death.”
Psalm 94:20-21 ESV
““Ah, stubborn children,” declares the Lord, “who carry out a plan, but not mine, and who make an alliance, but not of my Spirit, that they may add sin to sin;”
Isaiah 30:1 ESV
“Therefore thus says the Holy One of Israel, “Because you despise this word and trust in oppression and perverseness and rely on them, therefore this iniquity shall be to you like a breach in a high wall, bulging out and about to collapse, whose breaking comes suddenly, in an instant;”
Isaiah 30:12-13 ESV
“In that day the remnant of Israel and the survivors of the house of Jacob will no more lean on him who struck them, but will lean on the Lord, the Holy One of Israel, in truth. A remnant will return, the remnant of Jacob, to the mighty God. For though your people Israel be as the sand of the sea, only a remnant of them will return. Destruction is decreed, overflowing with righteousness.”
Isaiah 10:20-22 ESV
All of these verses cumulatively point to an end times covenant where Israel is aligning themselves with their neighboring nations that makes them completely vulnerable to a sudden invasion and being crushed in a day. Which is why Jesus is so adamant not to even look back to grab their coat. When these armies gather, the remnant will run.
