37 behold, I will put a fleece of wool on the threshing floor; if there be dew on the fleece only, and it be dry on all the ground, then shall I know that you will save Israel by my hand, as you have spoken.” 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.

Commentary on Judges 6:33-40
(Read Judges 6:33-40)
These signs are truly miraculous, and very significant. Gideon and his men were going to fight the Midianites; could God distinguish between a small fleece of Israel, and the vast floor of Midian? Gideon is made to know that God could do so. Is Gideon desirous that the dew of Divine grace might come down upon himself in particular? He sees the fleece wet with dew to assure him of it. Does he desire that God will be as the dew to all Israel? Behold, all the ground is wet. What cause we sinners of the Gentiles have, to bless the Lord that the dew of heavenly blessings, once confined to Israel, is now sent to all the inhabitants of the earth! Yet still the means of grace are in different measures, according to the purposes of God. In the same congregation, one man's soul is like Gideon's moistened fleece, another like the dry ground.
