Judges 6:36-38 New English Translation (NET Bible)
36 Gideon said to God, “If you really intend to use me to deliver Israel, as you promised, then give me a sign as proof. 37 Look, I am putting a wool fleece on the threshing floor. If there is dew only on the fleece, and the ground around it is dry, then I will be sure that you will use me to deliver Israel, as you promised.” 38 The Lord did as he asked. When he got up the next morning, he squeezed the fleece, and enough dew dripped from it to fill a bowl.
