ἐκτὸς [unique] (adv) "Outside" is the adverb ektos, which means "without", "outside,"with verbs of motion, "out," as a preposition, "out of", "far from", "beyond", "exempt from", "except", "without the consent of," as a noun, "external things", "strangers", "foreigners", "the vulgar," and "the common herd."  - "The outside" is from two Greek words like "that which is within" above. The first is the article, "the" and the second is the adverb that means "outside" and "without." Like the "within" above, this is from the same root words as the outside in the previous verse, but it is a different word. More interesting, this word has a number of special meanings when used as a noun as it is here. It means "external part," but it also means "outsider" and "the common people." This is likely why the word was changed here from the previous verse, since the word used previously does not have these meanings.
