Majority of Saints in Old Testament are Jewish

While it is true that the vast majority of figures recognized as "saints" in the Old Testament were Jewish, there are some exceptions. For example, Melchizedek, who is mentioned in the book of Genesis, is often understood by Christians to be a type of prefiguration of Christ, and is sometimes venerated as a saint in the Christian tradition.

Additionally, there are several non-Jewish figures in the Old Testament who are venerated as saints in some Christian traditions. For example, St. Job (or Jobab) is sometimes identified with the Job of the Old Testament, but is also believed by some to be a descendant of Esau and a king of Edom. Similarly, St. Jethro (or Reuel), who is identified as the father-in-law of Moses, is believed by some to have been a Midianite priest.

However, it is certainly true that the vast majority of figures recognized as "saints" in the Old Testament are Jewish, and that the Old Testament is primarily concerned with the religious and cultural traditions of the Jewish people.
