What was the first fleece test that Gideon gave to God?

To make a fleece wet while keeping the ground dry

Gideon said unto God ... I will put a fleece of wool in the floor; and if the dew be on the fleece only, and it be dry upon all the earth beside, then shall I know that thou wilt save Israel by mine hand, as thou hast said. And it was so: for he rose up early on the morrow, and thrust the fleece together, and wringed the dew out of the fleece, a bowl full of water. Judges 6:36-38
