17Gideon answered, “If I have found favor in Your sight, give me a sign that it is You speaking with me.
18Please do not depart from this place until I return to You. Let me bring my offering and set it before You.” And the LORD said, “I will stay until you return.”
19So Gideon went in and prepared a young goat and unleavened bread and an ephah of flour. He placed the meat in a basket and the broth in a pot and brought them out to present to Him under the oak.
20And the angel of God said to him, “Take the meat and the unleavened bread, lay them on this rock, and pour out the broth.” And Gideon did so.
