Romans 11:25

I do not want you to be ignorant of this mystery, brothers, so that you will not be conceited: A hardening in part has come to Israel, until the full number of the Gentiles has come in.
BSB · Berean Standard Bible
For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
KJV · King James Version
For I don’t desire you to be ignorant, brothers, of this mystery, so that you won’t be wise in your own conceits, that a partial hardening has happened to Israel, until the fullness of the Gentiles has come in,

Note The word for “brothers” here and where context allows may also be correctly translated “brothers and sisters” or “siblings.”
