King James Version (KJV)
Thou therefore, son of man, prophesy, and smite {thine} hands together, and let the sword be doubled the third time, the sword of the slain: it {is} the sword of the great {men that are} slain, which entereth into their privy chambers. {hands...: Heb. hand to hand}
Modern English
“You therefore, son of man, prophesy, and strike your hands together. Let the sword be doubled the third time, the sword of the fatally wounded. It is the sword of the great one who is fatally wounded, which enters into their rooms.
