Ezra wrote, “The sons of Judah were Perez, Hezron, Carmi, Hur, and Shobal” (1 Chronicles 4:1). 
Do you know through which son of Judah, Jesus of Nazareth descended? 
In First Chronicles 4:2-8, Ezra showed more, but not all the descendants of Judah. Does that partial listing help you at all to know through whom the Christ would come?
