1 Samuel 17:32 KJV — And David said to Saul, Let no man’s heart fail because of him; thy servant will go and fight with this Philistine.
David didn’t fight Goliath the giant.
David went and fought Goliath the Philistine.
This Philistine.
One of many.
One of those without a covenant with Yahweh…who was foolish enough to attack those who did have a covenant with Yahweh.
No contest.
Don’t fight the giant, fight the Philistine.
