Rabbi Yehudah bar Shalom said: That night [when the angel appeared to Gideon] was the night of Passover, when he said, "And where are all His wonders?" (Judges 6:13) - where are the wonders that God did for our fathers on this night, when He struck the firstborn of Egypt and brought our fathers out from there rejoicing? And once Gideon argued in defense of Israel, the Holy One, blessed be He, said: It is fitting that I reveal Myself in My glory to him, as it is said, "And the LORD turned toward him and said, Go in this your strength" (Judges 6:14). The Holy One, blessed be He, said to him: You have within you the strength to argue in defense of Israel; by your merit they are redeemed, as it is said, "and you shall save Israel" (Judges 6:14).
He began to test [God] with the fleece, as it is said, "Let me test, I pray, but this once with the fleece" (Judges 6:39); what is written? "And it was so" (Judges 6:40). The Holy One does not attach His Name there. The Holy One said: The whole world is in distress and shall I attach My Name? As it is written, "For You are not a God who delights in wickedness; evil shall not dwell with You" (Psalms 5:5). But at the moment Gideon said, "Let there now be dryness upon the fleece alone" (Judges 6:39), the Holy One said: Since the dew is blowing and the world rejoices, I will attach My Name, as it is said, "And God did so that night" (Judges 6:40).
So too Jeremiah: when he prophesied words of comfort he attached the divine Name, as it is said, "Thus says the LORD, I remember for you the kindness of your youth" (Jeremiah 2:2); but in words of rebuke it is written, "The words of Jeremiah" (Jeremiah 1:1). So too Moses: over every utterance it is written, "And the LORD spoke"; but when he came to rebuke, it is written, "These are the words" (Deuteronomy 1:1).
This is what Scripture says: "And the remnant of Jacob shall be..." (Micah 5:6). That remnant is the one of whom the Holy One said to Elijah, "Yet I have left Me in Israel seven thousand..." (1 Kings 19:18); and they are the same who were set apart in the days of Gideon, when he said to the Holy One, "If You will save Israel by my hand, as You have spoken, behold, I will set out [a fleece]" (Judges 6:36-37). The Holy One said to him: I wrote, "I will be as the dew to Israel" (Hosea 14:6), and you said, dryness over all the earth? I will not do so - which is why it is not written "and God did so," but "and it was so," meaning it happened of itself. But when he said, "Let there now be dryness upon the fleece alone," at once "and God did so."
The Holy One said to him, "The people that are with you are too many; bring them down to the water" (Judges 7:4) - those who knelt on their knees to drink water would, willing or unwilling, bow down to idols, for the generation of Gideon worshiped reflections [in water]. The Holy One said to him: With three hundred men who lap I will save Israel; and of them He says, "Yet I have left in Israel...", and of them He says, "And the remnant of Jacob shall be..."
Rabbi Abbahu said in the name of Rabbi Simon in the name of Rabbi Yehoshua ben Levi: The commandment of the Omer stood by them in the days of Gideon, as it is said, "And Gideon came, and behold, a man telling a dream to his fellow... and behold, a round loaf of barley bread" (Judges 7:13). What is "a round loaf" [tzelil]? The rabbis say: because that generation was overshadowed [tzalal] by the righteous among them. And by what merit were they saved? By the merit of the round loaf of barley - and what is that? The commandment of the Omer.
