'Spirit' in the Bible

Thus says the Lord:“Behold, I am going to stir up and put into action [a fury] against BabylonAnd against the [rebellious] people of Leb-kamai (Chaldea)A destroying wind and hostile spirit;

Sharpen the arrows, take up the shields [and cover yourselves]!The Lord has stirred up the spirit of the kings of the Medes,Because His purpose concerning Babylon is to destroy it;For that is the vengeance of the Lord, vengeance [on Babylon] for [plundering and destroying] His temple.
