Is david who killed goliath a saint?

David, who famously defeated Goliath in the biblical account, is considered a significant figure in Judaism, Christianity, and Islam, but he is not formally recognized as a saint in the same way that many other biblical figures are. In Christianity, saints are typically individuals who have been canonized for their holiness and virtue. David is acknowledged for his leadership and devotion to God, and he is often referred to as "a man after God's own heart," but he is more commonly viewed as a king and prophet rather than a saint.
