Judges 6:39 in the King James Version
And Gideon said unto God, Let not thine anger be hot against me, and I will speak but this once: let me prove, I pray thee, but this once with the fleece; let it now be dry only upon the fleece, and upon all the ground let there be dew.
Context
38 It was so; for he rose up early on the next day, and pressed the fleece together, and wrung the dew out of the fleece, a bowl full of water.
39 Gideon said to God, “Don’t let your anger be kindled against me, and I will speak but this once. Please let me make a trial just this once with the fleece. Let it now be dry only on the fleece, and on all the ground let there be dew.”
40 God did so that night; for it was dry on the fleece only, and there was dew on all the ground.
