Judges 7:5-7

When Gideon took his warriors down to the water, the LORD told him, “Divide the men into two groups. In one group put all those who cup water in their hands and lap it up with their tongues like dogs. In the other group put all those who kneel down and drink with their mouths in the stream.” Only 300 of the men drank from their hands. All the others got down on their knees and drank with their mouths in the stream. The LORD told Gideon, “With these 300 men I will rescue you and give you victory over the Midianites. Send all the others home.”
