How to understand this crucial passage: "The only way to establish a common power that can defend them from the invasion of foreigners and the injuries of one another, and thereby make them secure enough to be able to nourish themselves and live contentedly through their own labours and the fruits of the earth, is to confer all their power and strength on one man, or one assembly of men, so as to turn all their wills by a majority vote into a single will." Note: the last bit of it states the defining power of a "sovereign."
