Judges 7:2-7

2The LORD said to Gideon, “You have too many men. I cannot deliver Midian into their hands, or Israel would boast against me, ‘My own strength has saved me.’

3Now announce to the army, ‘Anyone who trembles with fear may turn back and leave Mount Gilead.’ ” So twenty-two thousand men left, while ten thousand remained.

4But the LORD said to Gideon, “There are still too many men. Take them down to the water, and I will thin them out for you there. If I say, ‘This one shall go with you,’ he shall go; but if I say, ‘This one shall not go with you,’ he shall not go.” 5So Gideon took the men down to the water. There the LORD told him, “Separate those who lap the water with their tongues as a dog laps from those who kneel down to drink.”

6Three hundred of them drank from cupped hands, lapping like dogs. All the rest got down on their knees to drink. 7The LORD said to Gideon, “With the three hundred men that lapped I will save you and give the Midianites into your hands. Let all the others go home.”
