Goliat is a character from the biblical story found in the Book of 1 Samuel. He is described as a giant warrior from the Philistine army, known for his immense size and strength. Goliat challenged the Israelites to send out a champion to fight him in single combat, boasting of his superiority and instilling fear in his opponents. The most famous account of Goliat involves David, a young shepherd who volunteered to face him. Armed only with a sling and stones, David defeated Goliat with a single shot, striking him in the forehead. This victory symbolizes the triumph of faith and courage over seemingly insurmountable odds.
