Jesus’ final words make it clear that circumstances are changing. Opposition to the disciples is rising. Where before Jesus had sent them out empty-handed yet they were provided for (9:1-6; 10:3-4), now they will have to take provisions and protection for their travel. They will have to procure a sword. Scripture such as Isaiah 53:12 is finding its fulfillment in Jesus. Jesus is rejected; he is numbered with the transgressors.
The disciples take Jesus’ remarks literally and incorrectly. They note that they have two swords, but Jesus cuts off the discussion. Something is not right, but it is too late to discuss it. As the arrest will show, they have misunderstood. They draw swords then, but Jesus stops their defense in its tracks. He is not telling them to buy swords to wield in physical battle. They will have to provide for themselves and fend for themselves, but not through the shedding of blood. They are being drawn into a great cosmic struggle, and they must fight with spiritual swords and resources. The purchase of swords serves only to picture this coming battle. This fight requires special weapons (Eph 6:10-18). Humility, dependence, promise of authority and reward, warnings about opposition and the pursuit of faithfulness are the topics of Jesus’ final testament meal. Luke assumes that disciples will engage the larger world and face a great cosmic battle. But they are not to withdraw or be afraid. Rather, with humility and looking to God, they can face suffering and the world bravely and effectively. Jesus is about to exemplify the walk of the innocent before a hostile world. His success is not indicated by his withdrawal or even his survival; it is indicated by his faithfulness (1 Pet 2:21-25).
