1 Samuel 17:8

And he stood and cried unto the armies of Israel, the divisions and companies as they were set up in battle array, and said unto them, Why are ye come out to set your battle in array? Am not I a Philistine and ye servants to Saul? Choose you a man for you, and let him come down to me, to the valley beneath the hillside where the Israelites were standing in battle-line.
