Judges 6:21

The angel - put forth the end of the staff - He appeared like a traveler with a staff in his hand; this he put forth, and having touched the flesh, fire rose out of the rock and consumed it. Here was the most evident proof of supernatural agency.

Then the angel - departed out of his sight - Though the angel vanished out of his sight, yet God continued to converse with him either by secret inspiration in his own heart, or by an audible voice.
