Judges 7:4-6

Young's Literal Translation

⁴ And Jehovah saith unto Gideon, `Yet [are] the people too many; bring them down unto the water, and I refine it for thee there; and it hath been, he of whom I say unto thee, This doth go with thee -- he doth go with thee; and any of whom I say unto thee, This doth not go with thee -- he doth not go.'

⁵ And he bringeth down the people unto the water, and Jehovah saith unto Gideon, `Every one who lappeth with his tongue of the water as the dog lappeth -- thou dost set him apart; also every one who boweth on his knees to drink.'

⁶ And the number of those lapping with their hand unto their mouth is three hundred men, and all the rest of the people have bowed down on their knees to drink water.
