3) That the saying might be fulfilled, which he spake, Of them which thou has gavest me have I lost none.

Lets not forget:
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.
If they didn't have swords, they wouldn't of had the ability to defend themselves and would have been placed in prison (or even worse), which repeatedly happens in Acts. No harm were to come to the disciples during that hour.
