'Spirit' in the Bible

It happened, when they had gone over, that Elijah said to Elisha, "Ask what I shall do for you, before I am taken from you." Elisha said, "Please let a double portion of your spirit be on me."

When the sons of the prophets who were at Jericho over against him saw him, they said, "The spirit of Elijah rests on Elisha." They came to meet him, and bowed themselves to the ground before him.

They said to him, "See now, there are with your servants fifty strong men. Please let them go and seek your master. Perhaps the Spirit of Yahweh has taken him up, and put him on some mountain, or into some valley. He said, "You shall not send them."

Behold, I will put a spirit in him, and he will hear news, and will return to his own land. I will cause him to fall by the sword in his own land."'"
