Question: where in the bible does it talk about birth of jesus?
Answer: Of the four canonical gospels, only two offer narratives regarding the birth of Jesus: Matthew (Matthew 1:18-25, plus a genealogy of Joseph at Matthew 1:1-17) and Luke (Luke 2:1-7, plus a genealogy of Joseph at Luke 3:21-38). Of these two, only Luke offers the details of Jesus' birth in Bethlehem.
