The angel of Yahweh came, and sat under the oak which was in Ophrah, that pertained to Joash the Abiezrite: and his son Gideon was beating out wheat in the winepress, to hide it from the Midianites.
"Where are all his wondrous works ...?"  (Judges 6:13).  This was Gideon's response to the greeting of the Angel of Jehovah who had said, "Jehovah is with thee"  (Judges 6:12), indicating that all Israelites were thoroughly familiar with all the wonders that God had wrought upon their behalf when He brought them up out of the land of Egypt.  (See also under  Judges 6:10 above.)
