'Themselves' in the Bible

And whereas thou sawest the iron mixed with miry clay, they shall mingle themselves with the seed of men; but they shall not cleave one to another, even as iron doth not mingle with clay.

And I, Daniel, alone saw the vision; for the men that were with me saw not the vision; but a great quaking fell upon them, and they fled to hide themselves.

And at the end of years they shall join themselves together; and the daughter of the king of the south shall come to the king of the north to make an agreement: but she shall not retain the strength of her arm; neither shall he stand, nor his arm; but she shall be given up, and they that brought her, and he that begat her, and he that strengthened her in those times.

And in those times there shall many stand up against the king of the south: also the children of the violent among thy people shall lift themselves up to establish the vision; but they shall fall.

Now when they shall fall, they shall be helped with a little help; but many shall join themselves unto them with flatteries.

Many shall purify themselves, and make themselves white, and be refined; but the wicked shall do wickedly; and none of the wicked shall understand; but they that are wise shall understand.
