Judges 6:36-38

³⁶Then Gideon said to God, “If You will deliver Israel through me, as You have spoken, ³⁷behold, I will 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 will know that You will deliver Israel through me, as You have spoken.” ³⁸And it was so. When he arose early the next morning and squeezed the fleece, he drained the dew from the fleece, a bowl full of water.
