Definition: The word "Alvar" is an ancient Hebrew term that can mean a person of royal or high standing, but it's not explicitly related to any specific biblical or literary text. It seems like you might have mistyped the name or context. If the question was about a king named Alvar in the Bible, that would be very different. The word "Alvar" is used metaphorically within the Bible. For instance, in 1 Samuel 24:23, it refers to David's father and one of the kings who served under Saul: "Then said Saul unto David his servant, I have heard of thy wisdom, and of the understanding of thy heart; so that thou hast appointed me king over Israel with thee. Therefore let him that shall be king of Israel, say, Thou art my son." This usage indicates a relationship between King David and some royal family in ancient times but it's not clear if this is any reference to a specific biblical person or event.
