Judges 6:36-40

So Gideon said to God, “If You will save Israel by my hand as You have said— look, I shall put a fleece of wool on the threshing floor; if there is dew on the fleece only, and it is dry on all the ground, then I shall know that You will save Israel by my hand, as You have said.” And it was so. When he rose early the next morning and squeezed the fleece together, he wrung the dew out of the fleece, a bowlful of water. Then Gideon said to God, “Do not be angry with me, but let me speak just once more: Let me test, I pray, just once more with the fleece; let it now be dry only on the fleece, but on all the ground let there be dew.” And God did so that night. It was dry on the fleece only, but there was dew on all the ground.
