Final answer:
Gideon asked God to wet and then dry a fleece as a sign to confirm that he should lead the Israelites against their enemies. This story is found in the Book of Judges in the Bible.
Step-by-step explanation:
The item that Gideon asked God to wet/dry to give him more courage was a fleece. This is found in the Bible, specifically in the Book of Judges. To test God's will, Gideon placed a fleece on the ground and asked that it be wet with dew while the ground remained dry, and then he reversed the request. This was a sign for Gideon to confirm God's support for him to lead the Israelites against the Midianites.
