28 U.S.C. § 453 — Oaths of justices and judges

Every federal justice or judge must take this oath or affirmation before doing any duties of the job: "I, ___ ___, do solemnly swear (or affirm) that I will administer justice without respect to persons, and do equal right to the poor and to the rich, and that I will faithfully and impartially discharge and perform all the duties incumbent upon me as ___ under the Constitution and laws of the United States. So help me God." In plain words: the judge promises to treat every person the same, no matter who they are; to treat poor people and rich people equally; and to do the job honestly and fairly, following the Constitution and the laws of the United States.
