Final answer:
The tribes of Dan and Ephraim are missing from the list of Jewish tribes in Revelation 7.
Step-by-step explanation:
The book of Revelation in the Bible mentions the names of twelve tribes of Israel, with each tribe represented by 12,000 individuals. However, not all tribes are mentioned in Revelation 7. The tribes that are missing from the list are the tribes of Dan and Ephraim.
The reason for their exclusion is not explicitly stated in the text. Some scholars believe that Dan and Ephraim may have been omitted because of historical or theological reasons. It's important to note that different interpretations exist, and this exclusion does not diminish the significance of the other tribes listed in Revelation 7.
