    of water like a dog, i.e., by putting the hand filled with water
    to the mouth. The dog drinks by shaping the end of his long thin
    tongue into the form of a spoon, thus rapidly lifting up water,

    with Gideon thus employed their hands and lapped the water out
    of their hands (Judg. 7:7).
