“And He said to them, “When I sent you without money bag, knapsack, and sandals, did you lack anything?” So they said, “Nothing.” Then He said to them, “But now, he who has a money bag, let him take it, and likewise a knapsack; and he who has no sword, let him sell his garment and buy one. For I say to you that this which is written must still be accomplished in Me: ‘And He was numbered with the transgressors.’ For the things concerning Me have an end.”
Luke 22:35-37
Why is it that an hour later Jesus told his disciples to put away their swords?
Jesus “gave notice of a very great change of circumstances now approaching. The disciples must not expect that their friends would be kind to them as they had been. Therefore, he that has a purse, let him take it, for he may need it. They must now expect that their enemies would be more fierce than they had been, and they would need weapons. At the time the apostles understood Christ to mean real weapons, but he spake only of the weapons of the spiritual warfare. The sword of the Spirit is the sword with which the disciples of Christ must furnish themselves.”(Matthew Henry commentary)
In the next verse, Jesus goes on to explain that scripture must be fulfilled. Luke 22:37 says, “For I tell you that this Scripture must be fulfilled in me: ’And he was numbered with the transgressors.’ For what is written about me has its fulfillment.” Here, Jesus is quoting from Isaiah 53:12, which predicts that Jesus would be “numbered with the transgressors.”
Why would Jesus be telling his disciples to buy literal swords if he was saying that the scriptures stated that he would be killed and be numbered with the transgressors?
