Judges 6:16-18

But the LORD said to him, “Surely I will be with you, and you shall defeat Midian as one man.” So Gideon said to Him, “If now I have found favor in Your sight, then show me a sign that it is You who speak with me. Please do not depart from here, until I come back to You, and bring out my offering and lay it before You.” And He said, “I will remain until you return.”
