'Dew' in the Bible

then take a look at this wool fleece that I'm placing on the threshing floor. If dew appears only on the fleece and it's dry on the ground all around it then I'll know that you'll deliver Israel by my efforts like you've said."

And that is what happened: When he got up early the next morning, he wrung out the fleece to drain the dew from it and extracted a bowl full of water.

Then Gideon told God, "Don't let yourself be angry with me! I want to ask you once again: please let me make a test with the fleece just once more. Cause it to be dry only on the fleece, but let there be dew all around on the ground."

And God did it just like that later that night. It was dry only on the fleece, but dew was all around on the ground.
