Judges 6:30-40

Then the men of the city said unto Joash, Bring out thy son, that he may die: because he hath cast down the altar of Baal, and because he hath cut down the grove that was by it. And Joash said unto all that stood against him, Will ye plead for Baal? will ye save him? he that will plead for him, let him be put to death whilst it is yet morning: if he be a god, let him plead for himself, because one hath cast down his altar. Therefore on that day he called him Jerubbaal, saying, Let Baal plead against him, because he hath thrown down his altar. Then all the Midianites and the Amalekites and the children of the east were gathered together, and went over, and pitched in the valley of Jezreel. But the Spirit of the LORD came upon Gideon, and he blew a trumpet; and Abi-ezer was gathered after him. And he sent messengers throughout all Manasseh; who also was gathered after him: and he sent messengers unto Asher, and unto Zebulun, and unto Naphtali; and they came up to meet them. And Gideon said unto God, If thou wilt save Israel by mine hand, as thou hast said, Behold, I will put a fleece of wool in the floor; and if the dew be on the fleece only, and it be dry upon all the earth beside, then shall I know that thou wilt save Israel by mine hand, as thou hast said. And it was so: for he rose up early on the morrow, and thrust the fleece together, and wringed the dew out of the fleece, a bowl full of water. And Gideon said unto God, Let not thine anger be hot against me, and I will speak but this once: let me prove, I pray thee, but this once with the fleece; let it now be dry only upon the fleece, and upon all the ground let there be dew. And God did so that night: for it was dry upon the fleece only, and there was dew on all the ground.
