Revelation 4:8 refers to God as κύριος, ὁ θεός, ὁ παντοκράτωρ, generally rendered Lord God Almighty. I'm interested in the last word: ὁ παντοκράτωρ. Would this have connoted omnipotence as the English rendering "Almighty" does?
If it's a compound word, I'm reasonably certain the first half of the word, παντο, means "all." But what does κράτωρ mean? Is παντοκράτωρ a word used outside of the NT at all? I'm curious too, for instance, how the LXX translates El-Shaddai, since that is typically rendered in modern English translations as "The Almighty" as well.
Can anyone shed light on the theological weight of this word in Revelation?
