Answer:
The young David was the one who defeated the giant Goliath.
Step-by-step explanation:
The biblical story narrated in 1 Samuel 17: 4-23; 21: 9 tells that Goliath was a Philistine warrior who measured approximately three meters and wore a mail coat of copper of approximately 57 kilograms and David was a young sheepherder who had previously had to face wild beasts but did not belong to the army of Israel, but had only visited the battle site to feed their brothers who belonged to the army of Israel.
Upon hearing that Goliath challenged the Israelites and their God to confront him, and learned that they had been doing it systematically for 40 days, he took a sling, charged stones and confronted him by giving him an accurate shot in the middle, with which the giant fell and David decapitated him. David years later he served as king of Israel.
