Judges 7:5 TLB

[5] So Gideon assembled them at the water. There the Lord told him, "Divide them into two groups decided by the way they drink. In Group 1 will be all the men who cup the water in their hands to get it to their mouths and lap it like dogs. In Group 2 will be those who kneel, with their mouths in the stream." Only three hundred of the men drank from their hands; all the others drank with their mouths to the stream.
