1 Samuel 17:41-42
41-42As the Philistine paced back and forth, his shield bearer in front of him, he noticed David. He took one look down on him and sneered—a mere youngster, apple-cheeked and peach-fuzzed.
43The Philistine ridiculed David. "Am I a dog that you come after me with a stick?" And he cursed him by his gods.
