The big deal of Matthews is that Jesus is a direct descendent of Abraham through Isaac, King David, Solomon and others. Finally in the lineage is Joseph who became the husband of Mary, the mother of Jesus.
As Mary was impregnated by the Holy Ghost Joseph did not know Mary sexually until after the birth of Jesus
Question — How does that make Jesus a descendant of Abraham and the others? It strikes me that the chain was broken with the “virgin” birth.
