'Themselves' in the Bible

For see, I am sending the Chaldaeans, that bitter and quick-moving nation; who go through the wide spaces of the earth to get for themselves living-places which are not theirs.

They are terrible and dreadful: their judgment and their dignity shall proceed of themselves.

Their horses also are swifter than the leopards, and are more fierce than the evening wolves: and their horsemen shall spread themselves, and their horsemen shall come from far; they shall fly as the eagle that hasteth to eat.

And they themselves scoff at kings and rulers [are] a joke to them. They laugh at every fortification, and they heap up earth and take it.

“Then they will sweep by like the wind and pass on.But they will be held guilty,They [and all men] whose own power and strength is their god.”

Behold, is it not of the LORD of hosts that the people shall labour in the very fire, and the people shall weary themselves for very vanity?

He hath stood, and He measureth earth, He hath seen, and He shaketh off nations, And scatter themselves do mountains of antiquity, Bowed have the hills of old, The ways of old are His.
