What is the meaning of the word “holy”?

Revelation 4:8 (ESV)

8 And the four living creatures, each of them with six wings, are full of eyes all around and within, and day and night they never cease to say, “Holy, holy, holy, is the Lord God Almighty, who was and is and is to come!”

While the creatures' song recalls the song of the seraphim in Isaiah 6:1–13, we are not to conclude that the use of the same song implies that this song is always heard in heaven over the centuries. The emphasis needs to lie instead on the use of the word “holy,” which denotes separateness, being different.
