Judges 6
11 (NIV) The angel of the LORD came and sat down under the oak in Ophrah that belonged to Joash the Abiezrite, where his son Gideon was threshing wheat in a winepress to keep it from the Midianites.  12 When the angel of the LORD appeared to Gideon, he said, "The LORD is with you, mighty warrior." 20 The angel of God said to him, "Take the meat and the unleavened bread, place them on this rock, and pour out the broth." And Gideon did so. 21 With the tip of the staff that was in his hand, the angel of the LORD touched the meat and the unleavened bread. Fire flared from the rock, consuming the meat and the bread. And the angel of the LORD disappeared. 22 When Gideon realized that it was the angel of the LORD, he exclaimed, "Ah, Sovereign LORD! I have seen the angel of the LORD face to face!"
