'Angel' in the Bible

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

And he lay down and slept under the broom-bush. And behold, an angel touched him, and said to him, Arise, eat!

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