I assume that you are looking for something more than the Matthew & Luke genealogies and the scripture that I cited from Acts 2 which says that Jesus is the fruit of David's body according to the flesh. If so, then your question may be beyond me. If I may, the point angelo is making is that the lineage from David passes down through Joseph. But that Joseph is not, biologically, Jesus' father.
