'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 am taken 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 that were at Jericho over against him 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 are with thy servants fifty strong men; let them go, we pray thee, and seek thy master, lest the Spirit of Jehovah hath taken him up, and cast him upon some mountain, or into some valley. And he said, Ye shall not send.

Behold, I will put a spirit in him, and he shall hear tidings, and shall return to his own land; and I will cause him to fall by the sword in his own land.
