Judges 6:36-39

Gideon said to God, “If you have really chosen me to rescue Israel, as you said, then give me proof. Here—I am placing a wool fleece on the threshing floor. If in the morning the dew is only on the wool but not on the ground around it, then I will know for sure that I’m the one you have chosen to rescue Israel, as you said.” And that is exactly what happened. When Gideon got up early the next morning, he squeezed the fleece and wrung out enough dew to fill a bowl. Then Gideon said to God, “Don’t be angry with me; let me speak just once more. Please let me ask you for one more sign. This time let the fleece be dry, and the ground wet.”
