The Story Of King David
The truth is that there is not much in the way of evidence of his existence. However, there are sources corroborating it as well. He is mentioned in the Bible and has appeared on several stone tablets. The basis for the history of the King of the Israelites mostly relies on those two sources.
Up Against Goliath
In reality, David was not always such a powerful figure. In fact, he only went on to lead the military after he won over Goliath with a slingshot. It was only then that he earned the title of King David. Once he claimed victory over Jerusalem, it became the capital of the Israelite.
