Judges 7:2-3 and 5-7

"And the Lord said to Gideon, 'The people who are with are too many for Me to give the Midianites into their hands, lest Israel claim glory for itself against Me, saying, "My own hand has saved me".'"

"'Now therefore, proclaim in the hearing of the people, saying, "Whoever is fearful and afraid, let him turn and depart at once from Mount Gilead."' And twenty-two thousand of the people returned, and ten thousand remained."

"So he brought the people down to the water. And the Lord said to Gideon, 'Everyone who laps from the water with his tongue, as a dog laps, you shall set apart by himself; likewise everyone who gets down on his knees to drink.'"

"And the number of those who lapped, putting their hand to their mouth, was three hundred men; but all the rest of the people got down on their knees to drink water."

"Then the Lord said to Gideon, 'By the three hundred men who lapped I will save you, and deliver the Midianites into your hand. Let all the other people go, every man to his place.'"
