Holy Mission, luke 9B
The ministry of proclamation is not limited to the Twelve. In 9:1-6 they were sent out on a mission to preach the kingdom, but now a larger group of seventy-two is sent. Jesus does not limit ministry to a select few (see 9:49-50, 60-61). Disciples are called to preach the hope of the kingdom. Luke 22:35 refers back to these instructions when Jesus is addressing the Twelve at the Last Supper. So it appears that the Twelve are part of the seventy-two. They travel two by two to prepare different towns for Jesus' arrival. It is clear from what Jesus says that the task ahead of them is large. There will be rejection, but they can also anticipate a large harvest.
