Judges 6:17-27

17 And he said to him, "If now I have found favor with thee, then show me a sign that it is thou who speakest with me.
18 Do not depart from here, I pray thee, until I come to thee, and bring out my present, and set it before thee." And he said, "I will stay till you return."
19 So Gideon went into his house and prepared a kid, and unleavened cakes from an ephah of flour; the meat he put in a basket, and the broth he put in a pot, and brought them to him under the oak and presented them.
20 And the angel of God said to him, "Take the meat and the unleavened cakes, and put them on this rock, and pour the broth over them." And he did so.
21 Then the angel of the LORD reached out the tip of the staff that was in his hand, and touched the meat and the unleavened cakes; and there sprang up fire from the rock and consumed the flesh and the unleavened cakes; and the angel of the LORD vanished from his sight.
22 Then Gideon perceived that he was the angel of the LORD; and Gideon said, "Alas, O Lord GOD! For now I have seen the angel of the LORD face to face."
23 But the LORD said to him, "Peace be to you; do not fear, you shall not die."
24 Then Gideon built an altar there to the LORD, and called it, The LORD is peace. To this day it still stands at Ophrah, which belongs to the Abiez'rites.
25 That night the LORD said to him, "Take your father's bull, the second bull seven years old, and pull down the altar of Ba'al which your father has, and cut down the Ashe'rah that is beside it;
26 and build an altar to the LORD your God on the top of the stronghold here, with stones laid in due order; then take the second bull, and offer it as a burnt offering with the wood of the Ashe'rah which you shall cut down."
27 So Gideon took ten men of his servants, and did as the LORD had told him; but because he was too afraid of his family and the men of the town to do it by day, he did it by night.
