'Spirit' in the Bible

So the God of Israel stirred up the spirit of Pul, king of Assyria, even the spirit of Tilgath-pilneser king of Assyria, and he carried them away into exile, namely the Reubenites, the Gadites and the half-tribe of Manasseh, and brought them to Halah, Habor, Hara and to the river of Gozan, to this day.

Then the Spirit came upon Amasai, who was the chief of the thirty, and he said,“We are yours, O David,And with you, O son of Jesse!Peace, peace to you,And peace to him who helps you;Indeed, your God helps you!”Then David received them and made them captains of the band.
