Why did Jesus send seventy-two disciples when He had twelve apostles? Study Luke 10 with context, apologetic analysis, and cross-references.
Dr. Lucas D. Shallua Commentary · Luke 10
The number seventy-two echoes the seventy elders of Israel and the seventy nations in Genesis 10. It signifies the breadth of the mission. The gospel is not for Israel alone; it is for all nations. The sending of the seventy-two is a preview of the Great Commission. Jesus is expanding the mission beyond the inner circle.
The exorcisms performed by the seventy-two were signs of a cosmic defeat. Satan's kingdom is being dismantled. The fall of Satan is not a single event but a process that began with his rebellion and is being completed through the ministry of Jesus. The cross and resurrection will seal his defeat. The disciples' authority over demons is a foretaste of the final victory.
Jesus is not diminishing the importance of spiritual authority. He is putting it in perspective. The greater joy is not what we do for God but what God has done for us. The assurance of salvation is greater than the exercise of power. The disciples' names are written in heaven. That is the source of true joy.
The parable of the Good Samaritan redefines the question. The lawyer asked, "Who is my neighbor?" Jesus answered by showing what it means to be a neighbor. The neighbor is anyone in need, regardless of race, religion, or social status. The one who shows mercy is the one who keeps the Law. The parable is not a definition of who deserves our love; it is a call to love without limits.
The priest and the Levite may have been concerned about ritual purity. If the man was dead, touching him would make them ceremonially unclean. They may have been on their way to serve in the temple. But their concern for ritual purity outweighed their compassion for a dying man. Jesus is exposing the hypocrisy of a religion that values rules over people.
Martha was distracted with much serving. She was anxious and troubled. Mary chose to sit at Jesus' feet and listen to His teaching. Jesus did not rebuke Martha for serving; He rebuked her for being anxious and troubled. The good portion is devotion to Jesus. Service flows from devotion, not the other way around. Mary chose the better part, and it would not be taken from her.
No. The lawyer's question, "What shall I do to inherit eternal life?" reveals a works-righteousness mentality. Jesus pointed him to the Law, which demands perfect love for God and neighbor. No one can keep the Law perfectly. The Law was given to show us our need for grace. The lawyer wanted to justify himself, but the parable of the Good Samaritan exposed his failure. He could not even identify with the Samaritan. The Law cannot save; it can only condemn.
Chapter 9 ended with Jesus setting His face toward Jerusalem and delivering three challenging sayings about the cost of discipleship. Now Luke presents a new phase of the journey. Jesus appoints seventy-two disciples and sends them ahead of Him into every town and place He is about to visit. The number seventy-two echoes the seventy elders of Israel in Exodus 24 and the seventy nations in Genesis 10. It signifies the breadth of the mission. The setting moves from the Galilean ministry to the Samaritan villages to Bethany. The chapter contains the parable of the Good Samaritan, one of the most famous stories in human history, and the account of Mary and Martha, which redefines devotion. Jesus is on the road to Jerusalem, and He is teaching His disciples what it means to follow Him.
Some critics argue that the parable of the Good Samaritan is a later Christian invention designed to promote universal ethics. But the parable is deeply rooted in the Jewish context of the first century. The road from Jerusalem to Jericho was notoriously dangerous. The priest and the Levite were real figures in Jewish society. The Samaritans were a real ethnic group with a long history of hostility with the Jews. Jesus' choice of a Samaritan as the hero of the parable would have been shocking to His Jewish audience. If the early church were inventing the story, they would not have made a Samaritan the hero. The most plausible explanation for this parable is that it preserves genuine historical memory. The mission of the seventy-two is also historically significant. The early church did not invent the mission to the Gentiles. It was commanded by Jesus. The seventy-two were sent ahead of Jesus into every town and place He was about to visit. The gospel spread from Jerusalem to Judea to Samaria to the ends of the earth. The most plausible explanation for this account is that it preserves genuine historical memory. The account of Mary and Martha is also historically plausible. The detail of Martha's distraction, Mary's posture at Jesus' feet, and Jesus' gentle rebuke are vivid and specific. The early church preserved this account because it illustrated the priority of devotion over service. The most plausible explanation for this account is that it preserves genuine historical memory.
This study preserves the hard questions, explanations, context, apologetic note, and references from Dr. Shallua's Commentary.
