Judges 7:6-8 (New International Version)
6 Three hundred men lapped with their hands to their mouths. All the rest got down on their knees to drink.
7 The 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 other men go, each to his own place.” 8 So Gideon sent the rest of the Israelites to their tents but kept the three hundred, who took over the provisions and trumpets of the others.
Now the camp of Midian lay below him in the valley.
