Titles for the Messiah
As we can see from the healing of the blind beggar in Luke, Chapter 18, there are a number of titles for the Messiah. Jews would recognise these instantly, and the blind man uses one of these - 'Son of David'. There are at least six others. Try using your computer search engine to find the others.
