Revelation 4:4 KJV
And round about the throne were four and twenty seats: and upon the seats I saw four and twenty elders sitting, clothed in white raiment; and they had on their heads crowns of gold.
Twenty four seats for twenty four elders.
I am reminded of the musical chairs game where there is always just one chair less than there are people. When the music stops playing and everyone has to sit, someone is always left out; the loser of that round.
Not so in heaven. There are enough seats to go around. Not too many or else someone might think they should have more, but just the right number that everyone is cared for and may therefore be content.
I imagine all of heaven is this way; not only with seats but with every need and want.
