Judges. Gedeon.

Douay-Rheims translation

6:11 Then the angel of the LORD came and sat under the oak that was in Ophrah, which belonged to Joash the Abiezrite as his son Gideon was beating out wheat in the wine press in order to save it from the Madianites.
6:12 The angel of the LORD appeared to him and said to him, "The LORD is with you, O valiant warrior."
6:13 Then Gideon said to him, "O my lord, if the LORD is with us, why then has all this happened to us? And where are all His miracles which our fathers told us about, saying, 'Did not the LORD bring us up from Egypt?' But now the LORD has abandoned us and given us into the hand of Madian."
6:14 The LORD looked at him and said, "Go in this your strength and deliver Israel from the hand of Madian. Have I not sent you?"
6:15 He said to Him, "O Lord, how shall I deliver Israel? Behold, my family is the least in Manasseh, and I am the youngest in my father's house."
6:16 But the LORD said to him, "Surely I will be with you, and you shall defeat Madian as one man."

7:2 And the Lord said to Gedeon: The people that are with thee are many, and Madian shall not be delivered into their hands: lest Israel should glory against me, and say: I was delivered by my own strength.
7:3 Speak to the people, and proclaim in the hearing of all, I Whosoever is fearful and timorous, let him return. So two and twenty thousand men went away from mount Galaad and returned home, and only ten thousand remained.
7:4 And the Lord said to Gedeon: The people are still too many, bring them to the waters, and there I will try them: and of whom I shall say to thee, This shall go with thee, let him go: whom I shall forbid to go, let him return.
7:5 And when the people were come down to the waters, the Lord said to Gedeon: They that shall lap the water with their tongues, as dogs are wont to lap, thou shalt set apart by themselves: but they that shall drink bowing down their knees, shall be on the other side.
7:6 And the number of them that had lapped water, casting it with the hand to their mouth, was three hundred men: and all the rest of the multitude had drunk kneeling.
7:7 And the Lord said to Gedeon: By the three hundred men, that lapped water, I will save you, and deliver Madian into thy hand: but let all the rest of the people return to their place.
