Nathan (son of David) in Wikipedia
Nathan (Hebrew: נתן, Modern Natan Tiberian Nāṯān) was the
third of four sons born to King David and Bathsheba in
Jerusalem. He was an older brother of Solomon.
In the New Testament, the genealogy of Jesus according to the
Gospel of Luke traces Jesus' lineage back to King David
through the line of Nathan, although the Gospel of Matthew
traces it through Solomon.
Nathan is also mentioned to be the son of David in 2 Samuel
5:14, & 1 Chronicles 3:5 & 14:4.
