Saul said to David, You are not able to go against this Philistine to fight with him; for you are but a youth, and he a man of war from his youth.
"The opposite of the fear of the Lord is the fear of man. No greater contrast of these opposing fears could be presented than when David confronted Goliath. Saul and his men feared Goliath the man, but David by virtue of his fear of Yahweh did not."
