The caution of Gideon, desirous of being assured that he really had a promise from God, does not imply doubts as to God's faithfulness or power to fulfill His promise. Of such doubts there is not a trace in Gideon's character. He is a worthy example of faith Hebrews 11:32.

If thou wilt save Israel - Gideon was very bold, and God was very condescending. But probably the request itself was suggested by the Divine Spirit. On the miracle of the fleece, dew, and dry ground, Origen, in his eighth homily on the book of Judges, has many curious and interesting thoughts, I shall insert the substance of the whole: - The fleece is the Jewish nation. The fleece covered with dew, while all around is dry, the Jewish nation favored with the law and the prophets. The fleece dry, the Jewish nation cast off for rejecting the Gospel. All around watered, the Gospel preached to the Gentiles. and they converted to God. The fleece on the threshing-floor, the Jewish people in the land of Judea, winnowed, purged, and fanned by the Gospel. The dew wrung out into the bowl, the doctrines of Christianity, extracted from the Jewish writings, shadowed forth by Christ's pouring water into a basin, and washing the disciples' feet. The pious father concludes that he has now wrung this water out of the fleece of the book of Judges, as he hopes by and by to do out of the fleece of the book of Kings, and out of the fleece of the book of Isaiah or Jeremiah; and he has received it into the basin of his heart, and there conceived its true sense; and is desirous to wash the feet of his brethren, that they may be able to walk in the way of the preparation of the Gospel of peace. - Origen, Op. vol. ii., p. 475, edit. Benedict. All this to some will doubtless appear trifling; but it is not too much to say that scarcely any pious mind can consider the homily of this excellent man without drinking into a measure of the same spirit, so much sincerity, deep piety, and unction, appear throughout the whole: yet as I do not follow such practices, I cannot recommend them. Of dealers in such small wares, we have many that imitate Benjamin Keach, but few that come nigh to Origen.

And Gideon said unto God,.... Not to a prophet of God who was there, of whom he asked the following signs to be done, as Ben Gersom, but to God in prayer, as Abarbinel:

if thou wilt save Israel by mine hand, as thou hast said; not that he doubted of it, but was willing to have a confirmation of his faith; and perhaps his view was more for the encouragement of those that were with him than himself, that he desired the following signs; and though he had had one before, that was to show that he was truly an angel that spoke to him, and not to ascertain the salvation that should be wrought by him; though that might be concluded from his being an angel that spoke to him, and assured him of it.

But before Gideon went into the battle with the assembled army, he asked for a sign from God of the success of his undertaking. "If Thou," he said to God, "art saving Israel through my hand, as Thou hast said, behold, I lay this fleece of wool upon the floor; if there shall be dew upon the fleece only, and dryness upon all the earth (round about), I know (by this) that Thou wilt save," etc. הצּמר גּזּת, the shorn of the wool; i.e., the fleece, the wool that had been shorn off a sheep, and still adhered together as one whole fleece. The sign which Gideon asked for, therefore, was that God would cause the dew to fall only upon a shorn fleece, which he would spread the previous night upon the floor, that is to say, upon some open ground, and that the ground all round might not be moistened by the dew.

And Gideon said unto God, {p} If thou wilt save Israel by mine hand, as thou hast said,

(p) This request proceeds not from infidelity, but that he might be confirmed in his calling.

6:36 Gideon said - In a way of humble supplication, for the strengthening his own faith, and for the greater encouragement of his soldiers in this great attempt.

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.
