Judges 6:36-39

³⁶And Gideon said to God, If thou wilt save Israel by my hand, as thou hast said,

³⁷Behold, I will put a fleece of wool on the floor; and if the dew shall be on the fleece only, and it shall be dry upon all the earth besides , then shall I know that thou wilt save Israel by my hand, as thou hast said.

³⁸And it was so: for he rose early on the morrow, and pressed the fleece, and wrung the dew out of the fleece, a bowl-full of water.

³⁹And Gideon said to God, Let not thy anger be hot against me, and I will speak but this once: Let me make trial, 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.
