What does Mark 7:25 mean?
The account in Matthew 15 gives more flesh to Mark's bare-bones narrative. The woman cries out, "Have mercy on me, O Lord, Son of David; my daughter is severely oppressed by a demon" (Matthew 15:22). She falls at His feet, a humble act duplicated by only a few amongst the many jostling crowds. She enters a private residence to see Him, an act Jesus sees as bold and faithful (Mark 2:1–5; Matthew 15:28).It's likely she heard of Jesus from early on in His ministry. At some point around the time He finalized His twelve disciples, Jesus was nearly crushed by a large crowd "from Galilee and Judea and Jerusalem and Idumea and from beyond the Jordan and from around Tyre and Sidon" (Mark 3:7–8). She would have heard that Jesus can both heal and exorcise demons (Mark 3:10–11).
Most striking, however, is that she calls Jesus "O Lord, Son of David." "Lord" could refer to an understanding that Jesus is God, but it more likely means she is submitting to Him as an authority. "Son of David" has only one meaning: Jesus is the promised descendent of David who will sit on the throne forever—He is the Jewish Messiah. How a Canaanite woman came to understand this about Jesus is unknown. How she understood it when the scribes and Pharisees, experts of the Jewish Scriptures, did not is mind-boggling.
