And He said unto them,
“When I sent you without purse, and scrip, and shoes, lacked ye any thing?”
And they said, “Nothing.” Then said He unto them,
“But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one. For I say unto you, that this that is written must yet be accomplished in Me, ‘And He was reckoned among the transgressors:’ for the things concerning Me have an end.”
And they said, “Lord, behold, here are two swords.” And He said unto them,
“It is enough.” Luke 22:35-38

There are some who want to give this as being an aggressive word from Jesus. It is not. He is warning His disciples and all His people that there was coming a time when we might need to defend ourselves; so be ready.

We are not to attack, whether by word, or by sword; but we can defend.

An even greater thing to glean from the words of Jesus is that we need to be strong and faithful to Him in every situation this world throws at us.
