The old testament describes the Philistines as being huge bullies, willing and able to take on anything and everything, until they came upon a shepherd boy named David.
1Samuel 17: 4-7 A champion named Goliath, who was from Gath, came out of the Philistine camp. His height was six cubits and a span. He had a bronze helmet on his head and wore a coat of scale armor of bronze weighing five thousand shekels[b]; 6 on his legs he wore bronze greaves, and a bronze javelin was slung on his back. His spear shaft was like a weaver’s rod, and its iron point weighed six hundred shekels. His shield bearer went ahead of him.
1Samuel 17:34-38 49
But David said to Saul, “Your servant has been keeping his father’s sheep. When a lion or a bear came and carried off a sheep from the flock, 35 I went after it, struck it and rescued the sheep from its mouth. When it turned on me, I seized it by its hair, struck it and killed it. Your servant has killed both the lion and the bear; this uncircumcised Philistine will be like one of them, because he has defied the armies of the living God The Lord who rescued me from the paw of the lion and the paw of the bear will rescue me from the hand of this Philistine.”
Saul said to David, “Go, and the Lord be with you.”
As the Philistine moved closer to attack him, David ran quickly toward the battle line to meet him. Reaching into his bag and taking out a stone, he slung it and struck the Philistine on the forehead. The stone sank into his forehead, and he fell face down on the ground.
