The Bible does not provide explicit details about the duration of Mary and Joseph's marriage. However, it is widely believed and accepted by Christian tradition that they remained married until Joseph's death. The New Testament Gospels, specifically Matthew and Luke, mention Joseph as being present during Jesus' early life, including his birth in Bethlehem and the events that followed.
After Jesus' birth, there are no mentions of Joseph during his adult ministry, leading many to speculate that Joseph may have passed away before that time. The Bible does not explicitly record Joseph's death, and it remains a mystery.
Christian tradition generally holds that Mary and Joseph had a loving and faithful marriage until Joseph's presumed passing. However, as with many aspects of biblical history, the exact details are not provided, leaving room for interpretation and belief based on faith and tradition.
