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; 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." 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.
When the men of the town rose early in the morning, behold, the altar of Ba'al was broken down, and the Ashe'rah beside it was cut down, and the second bull was offered upon the altar which had been built. And they said to one another, "Who has done this thing?" And after they had made search and inquired, they said, "Gideon the son of Jo'ash has done this thing." Then the men of the town said to Jo'ash, "Bring out your son, that he may die, for he has pulled down the altar of Ba'al and cut down the Ashe'rah beside it."
But Jo'ash said to all who were arrayed against him, "Will you contend for Ba'al? Or will you defend his cause? Whoever contends for him shall be put to death by morning. If he is a god, let him contend for himself, because his altar has been pulled down." Therefore on that day he was called Jerubba'al, that is to say, "Let Ba'al contend against him," because he pulled down his altar.
Then all the Mid'ianites and the Amal'ekites and the people of the East came together, and crossing the Jordan they encamped in the Valley of Jezreel. But the Spirit of the LORD took possession of Gideon; and he sounded the trumpet, and the Abiez'rites were called out to follow him. And he sent messengers throughout all Manas'seh; and they too were called out to follow him. And he sent messengers to Asher, Zeb'ulun, and Naph'tali; and they went up to meet them.
Then Gideon said to God, "If thou wilt deliver Israel by my hand, as thou hast said, behold, I am laying a fleece of wool on the threshing floor; if there is dew on the fleece alone, and it is dry on all the ground, then I shall know that thou wilt deliver Israel by my hand, as thou hast said."
And it was so. When he rose early next morning and squeezed the fleece, he wrung enough dew from the fleece to fill a bowl with water. Then Gideon said to God, "Let not thy anger burn against me, let me speak but this once; pray, let me make trial only this once with the fleece; pray, let it be dry only on the fleece, and on all the ground let there be dew." And God did so that night; for it was dry on the fleece only, and on all the ground there was dew.
