Thematic Bible: Lapping water

Then the Lord said to Gideon, "There are still too many people. Take them down to the water, and I will test them for you there. If I say to you, 'This one can go with you,' he can go. But if I say about anyone, 'This one cannot go with you,' he cannot go." So he brought the people down to the water, and the Lord said to Gideon, "Separate everyone who laps water with his tongue like a dog. Do the same with everyone who kneels to drink." The number of those who lapped with their hands to their mouths was 300 men, and all the rest of the people knelt to drink water. read more.
