from Galatians 6:

11Ye see how large a letter I have written unto you with mine own hand. 12As many as desire to make a fair shew in the flesh, they constrain you to be circumcised; only lest they should suffer persecution for the cross of Christ. 13For neither they themselves who are circumcised keep the law; but desire to have you circumcised, that they may glory in your flesh. 14But God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world. 15For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature.

16And as many as walk according to this rule, peace be on them, and mercy, and upon the Israel of God.

Seems like there's an Israel NOT of God, and a different one, which Paul calls the Israel of God. Hmm. Wonder who the other one belongs to...
