'Angel' in the Bible

And he said unto him, I also am a prophet as thou art; and an angel spake unto me by the word of Jehovah, saying, Bring him back with thee into thy house, that he may eat bread and drink water. But he lied unto him.

And he lay down and slept under a juniper-tree; and, behold, an angel touched him, and said unto him, Arise and eat.

And the angel of Jehovah came again the second time, and touched him, and said, Arise and eat, because the journey is too great for thee.
