Judges 7:5
"So he brought the people down to the water. And the Lord said to Gideon, ' Everyone who laps from the water with his tongue, as a dog laps, you shall set apart by himself. Likewise everyone who gets down on his knees to drink."
The end result is that those who forgot themselves and focussed on the water where sent home. Those who drank from their hands were called to battle. 300 of them to be exact, against a multitude.
Dog-lappers = untrained or inexperienced soldiers?
Interesting passage, but I don't think they're that familiar with the Bible.
