I think the whole of scripture is about mankind, not Israel. Israel was created to bless all mankind, both by the Messiah coming from Israel and that Israel showed the nations the Lord. That was their mission.
Gen. 12: 1-3 Now he Lord said
1 to Abram, “Go from your country
2 and your kindred and your father’s house to the land that I will show you. 2 And I will make of you a great nation, and I will bless you and make your name great, so that you will be a blessing. 3
oI will bless those who bless you, and him who dishonors you I will curse, and i
n you all the families of the earth shall be bless
