'Themselves' in the Bible

Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.

But these speak evil of those things which they know not: but what they know naturally, as brute beasts, in those things they corrupt themselves.

Woe to them! For they have traveled in the way of Cain, have abandoned themselves to the error of Balaam for profit, and have perished in Korah’s rebellion.

These are spots in your feasts of charity, when they feast with you, feeding themselves without fear: clouds they are without water, carried about of winds; trees whose fruit withereth, without fruit, twice dead, plucked up by the roots;

These be they who separate themselves, sensual, having not the Spirit.
