What is the significance of the "Seed of David" in biblical prophecy and how does it relate to the lineage of Jesus Christ?

The "Seed of David" in biblical prophecy refers to the descendant of King David who was prophesied to be a future ruler. In the New Testament, Jesus Christ is often referred to as the "Seed of David" because he is believed to be a direct descendant of King David through his earthly lineage. This connection is significant because it fulfills the Old Testament prophecies about a messianic figure coming from the line of David to establish a kingdom that will last forever.
