But let each one test his own work, and then he will have reason to boast in himself alone, and not in his neighbor.

For those who are circumcised do not even keep the Law themselves, but they desire to have you circumcised so that they may boast in your flesh.

But may it never be that I would boast, except in the cross of our Lord Jesus Christ, through which the world has been crucified to me, and I to the world.
