Seems pretty normal to me .... after all at least one of Jesus' disciples carried a sword, right?
Yeah--in fact, the apostles were able to sprout two of them in pretty short order:
"And [Jesus] said to them, 'But now, whoever has a money belt is to take it along, likewise also a bag, and whoever has no sword is to sell his coat and buy one. . . .' They [the apostles] said, 'Lord, look, here are two swords.' And He said to them, 'It is enough.'"
--Luke 22:36-38
. . . Nor were they disinclined to use them:
[At Jesus' arrest in the Garden of Gethsemane, just outside Jerusalem:]
"But one of those who stood by drew his sword, and struck the slave of the high priest and cut off his ear."
--Mark 14:47
The same incident, as reported in the Gospel of John:
"Simon Peter then, having a sword, drew it and struck the high priest's slave, and cut off his right ear; and the slave's name was Malchus. So Jesus said to Peter, 'Put the sword into the sheath; the cup which the Father has given Me, shall I not drink it?'"
--John 18:10-11.
While we're at it, check out the following:
Ancient sword-control law (didn't work then, either):
"Now no blacksmith could be found in all the land of Israel, for the Philistines said, 'Otherwise the Hebrews will make swords or spears.' So all Israel went down to the Philistines, each to sharpen his plowshare, his mattock, his axe, and his hoe. The charge was two-thirds of a shekel for the plowshares, the mattocks, the forks, and the axes, and to fix the hoes. So it came about on the day of battle that neither sword nor spear was found in the hands of any of the people who were with Saul and Jonathan, but they were found with Saul and his son Jonathan."
--1st Samuel 13:19-22
And lest you think Bill Bagwell was the first person to advocate concealed carry of a big Bowie knife with a functional back edge:
"Ehud made himself a sword which had two edges, a cubit [= about 18 inches] in length, and he bound it on his right thigh under his cloak."
--Judges 3:16 [in subsequent verses, Ehud uses this blade to dispatch the wicked King Eglon of Moab.]
