Judges 6:36-40 - Gideon Tests Yahweh With The Fleece
36 And Gideon said unto God, Wilt thou save Israel by my hand as thou hast said? 37 Behold, I will put a fleece of wool in the threshing floor; and if the dew is on the fleece only and it is dry upon all the earth beside it, then I shall know that thou wilt save Israel by my hand as thou hast said. 38 And it was so, for he rose up early in the morning, and wringing the fleece, he took the dew out of it, a bowl full of water.
39 But Gideon said unto God, Let not thine anger be hot against me if I speak again on this occasion; only let me prove again now with the fleece. I pray thee, let it be dry only upon the fleece, and upon all the ground let there be dew. 40 And God did so that night for it was dry upon the fleece only, and there was dew on all the ground.
