'Itself' in the Bible

'And no one doth put new wine into old skins, and if otherwise, the new wine will burst the skins, and itself will be poured out, and the skins will be destroyed;

And he, knowing their thoughts, said to them, 'Every kingdom having been divided against itself is desolated; and house against house doth fall;

then doth it go, and take to it seven other spirits more evil than itself, and having entered, they dwell there, and the last of that man becometh worst than the first.'
