how old is david

David, the biblical King of Israel, is believed to have been around 70 to 71 years old when he died. He became king at the age of 30 and reigned for 40 years. His age during significant events such as being anointed as king is estimated to be between 10 and 15 years when anointed and about 16 to 19 years old when he fought Goliath, still a teenager at that time. These ages are inferred from biblical accounts and timelines.
