A more thorough explanation: “Oath-helper” is a term used in legal contexts to refer to a person who assists another individual in taking an oath or making a sworn statement. The oath-helper is typically present to provide support and ensure that the person taking the oath understands the significance and seriousness of the oath they are making.
Example: I solemnly swear to tell the truth, the whole truth, and nothing but the truth, with the assistance of my oath-helper.
