+1 Tommygunn and lions. Here's the passage:
Luke 22:35
35 And he said unto them, When I sent you without purse, and scrip, and shoes, lacked ye any thing? And they said, Nothing.
36 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.
37 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.
38 And they said, Lord, behold, here [are] two swords. And he said unto them, It is enough.
39 ¶ And he came out, and went, as he was wont, to the mount of Olives; and his disciples also followed him.

Luke 22:47
47 ¶ And while he yet spake, behold a multitude, and he that was called Judas, one of the twelve, went before them, and drew near unto Jesus to kiss him.
48 But Jesus said unto him, Judas, betrayest thou the Son of man with a kiss?
49 When they which were about him saw what would follow, they said unto him, Lord, shall we smite with the sword?
50 And one of them smote the servant of the high priest, and cut off his right ear.
51 And Jesus answered and said, Suffer ye thus far. And he touched his ear, and healed him.
52 Then Jesus said unto the chief priests, and captains of the temple, and the elders, which were come to him, Be ye come out, as against a thief, with swords and staves?
Pretty clear that Christ's disciples went armed and were willing to use their arms for defense.
