'Spirit' in the Bible

And it came to pass, when they were gone over, that Elijah said unto Elisha, Ask what I shall do for thee, before I be taken away from thee. And Elisha said, I pray thee, let a double portion of thy spirit be upon me.

And when the sons of the prophets which were to view at Jericho saw him, they said, The spirit of Elijah doth rest on Elisha. And they came to meet him, and bowed themselves to the ground before him.

And they said unto him, Behold now, there be with thy servants fifty strong men; let them go, we pray thee, and seek thy master: lest peradventure the Spirit of the LORD hath taken him up, and cast him upon some mountain, or into some valley. And he said, Ye shall not send.
