'Spirit' in the Bible

This is the word of the Lord to Zerubbabel, saying, Not by force or by power, but by my spirit, says the Lord of armies.

Then crying out to me, he said, See, those who are going to the north country have given rest to the spirit of the Lord in the north country.

The word of the Lord about Israel. The Lord by whom the heavens are stretched out and the bases of the earth put in place, and the spirit of man formed inside him, has said:

And I will send down on the family of David and on the people of Jerusalem the spirit of grace and of prayer; and their eyes will be turned to the one who was wounded by their hands: and they will be weeping for him as for an only son, and their grief for him will be bitter, like the grief of one sorrowing for his oldest son.

And it will come about on that day, says the Lord of armies, that I will have the names of the images cut off out of the land, and there will be no more memory of them: and I will send all the prophets and the unclean spirit away from the land.
