'By The Spirit' in the Bible

And Saul changed his clothes and put on other raiment; and then went he, and two men with him, and they came to the woman by night. And he said, "Prophesy unto me by the spirit, and bring me him up whom I shall name unto thee."

But the wind took me up, and in a vision which came by the spirit of God it brought me again into Chaldea among the prisoners. Then the vision that I had seen vanished away from me.
