Judges 6:16-18

And the LORD said to him, “Surely I will be with you, and you shall defeat the Midianites as one man.” Then he said to Him, “If now I have found favor in Your sight, then show me a sign that it is You who talk with me. Do not depart from here, I pray, until I come to You and bring out my offering and set it before You.” And He said, “I will wait until you come back.”
