Exodus 22:2-3 tells us "If the thief is found breaking in, and he is struck so that he dies, there shall be no guilt for his bloodshed. If the sun has risen on him, there shall be guilt for his bloodshed. He should make full restitution; if he has nothing, then he shall be sold for his theft."
We must also consider what Christ told his disciples in his last hours with them: "...But now, he who has a money bag, let him take it, and likewise a sack; and he who has no sword, let him sell his garment and buy one" (Luke 22:36). Keep in mind that the sword was the finest offensive weapon available to an individual soldier -- the equivalent then of a military rifle today.
The Israelite army was a militia army (Numbers 1:3, ff.) which came to battle with each man bearing his own weapons -- from the time of Moses, through the Judges, and beyond. When threatened by the Midianites, for example, "Moses spoke to the people , saying, 'Arm some of yourselves for the war, and let them go against the Midianites to take vengeance for the Lord on Midian'" (Numbers 31:3).
Again, to demonstrate the Biblical heritage of individuals bearing and keeping arms, during David's time in the wilderness avoiding capture by Saul, "David said to his men, 'Every man gird on his sword.' So every man girded on his sword, and David also girded on his sword" (1 Samuel 25:13).
Those who built on the wall, and those who carried burdens loaded themselves so that with one hand they worked at construction, and with the other held a weapon. Every one of the builders had his sword girded at his side as he built (Nehemiah 4:17-18).
Interesting collection of words. Christians need a jihad of their own.
