The LORD said to Gideon, “There are still too many people.
Bring them down to the water, and I will test them for you there.
It shall be, that those whom I tell you, ‘This shall go with you,’ shall go with you; and whoever I tell you, ‘This shall not go with you,’ shall not go.”
So he brought down the people to the water; and the LORD said to Gideon, “Everyone who laps of the water with his tongue, like a dog laps, you shall set him by himself; likewise everyone who bows down on his knees to drink.”
