Butch, you asked this, "That's because it's about Israel. Where do you see it not about Israel?" I think you just answered your own question. It's not about Israel only, it's about the two, Jew & Gentile's brought together. Therefore what verse one is speaking about applies to both. I'm interested in Verse one....
Ephesians 1:3 "Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places,
1:4 even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. In love
1:5 he predestined us for adoption as sons through Jesus Christ, according to the purpose of his will."
If it's about both then Isn't it about Israel? Verse 5 is about the Jews. As I've pointed out several times Paul references two groups, us and you. He explains clearly in chapter 2 that the group called "you" is the Gentiles. Therefore the other group, "us" is someone else. The statements in verses 3-12 tell us who the "us" group is, it's the Jews. It was the Jews who first trusted in the Christ. It was the Jews to whom God had given an inheritance. Notice that Paul said they had received an inheritance, past tense. The Gentiles had never received an inheritance from God. In verse 14 Paul speaks of a future inheritance of believers, it's future, not past. The past inheritance was to the Jews.
54 `And you shall divide the land by lot
as an inheritance among your families; to the larger you shall give a larger inheritance, and to the smaller you shall give a smaller inheritance; there everyone's inheritance shall be whatever falls to him by lot. You shall inherit according to the tribes of your fathers. (Num. 33:54 NKJ)
This is what Paul is talking about in Ephesians.
It was the Jews who were predestined to adoption.
22 "Then you shall say to Pharaoh,`Thus says the LORD:
"Israel is My son, My firstborn. (Exod. 4:22 NKJ)
The promise was to Abraham and his seed. Because Abraham obeyed God, God promised certain things to him. The Gentiles are made part of that through Christ. It is through Christ, by being grafted into the cultivated olive tree that the Gentiles become partakers of the promises to Abraham. Paul goes into detail about this in Galatians 3.

He chose us in Him before the foundation of the world, that we should
be holy and without blame before Him in love, (Eph. 1:4 NKJ)

holy people unto the LORD thy God: the LORD thy
God hath chosen thee to be a special people unto himself, above all people that are upon the face of the earth. (Deut. 7:6 KJV)
2 For thou art an
holy people unto the LORD thy God, and
the LORD hath chosen thee to be a peculiar people unto himself, above all the nations that are upon the earth. (Deut. 14:2 KJV)
Paul
6 To the praise of the glory
of his grace, wherein he hath made us
accepted in the beloved. (Eph. 1:1 KJV)
Accepted isn't the best translation the word actually means to pursue with grace. That's what God did for Israel.

OT realization.
God did this down through time with the prophets. He gave Israel prophet after prophet who came saying, "thus saith the Lord".
