'Angel of God' in the Bible

The Angel of God said to him, “Take the meat with the unleavened bread, put it on this stone, and pour the broth on it.” And he did so.

Then the woman went and told her husband, “A man of God came to me. He looked like the awe-inspiring Angel of God. I didn’t ask Him where He came from, and He didn’t tell me His name.

God listened to Manoah, and the Angel of God came again to the woman. She was sitting in the field, and her husband Manoah was not with her.
