KnowMe, since no one else listed the actual names I will give you the points for knowing where to find the answer. Good Job! Your turn to ask the next question. Make it challenging please. I love it when I learn something new.
Bye the way... The next time you read Rev 5 and see that the 24 crowned elders sing the song, "you have redeemed US by your blood from every tribe tongue, people, nation and has made us kings and priests, could be a symbolic representation of all glorified saints and not 24 special people. Maybe they are shown as 24 elders to suggest that we are going to rule and reign with him as Kings and Priests". That these 24 priest elders in 1 Chron 24 7-18 is what is supposed to be represented there in Rev 5. Not the actual named men but the idea of the government of the priesthood. This is not a private interpretation. I read about it first in the writings of Joseph A Seiss, in his verse by verse commentary on Revelation.
