I am arguing from the position that the taking of life of an individual who has done no harm to you or anyone, is murder.
So when Joshua killed every woman and child in Ai, after having already conquered the city, he comitted murder.
Now the Old Testamaent tells us that Joshua did this at the command of God.
Of course the 9-11 hijackers told us the same thing.
I understand that. However that is not the operating definition used in the Bible. Joshua did not murder as it was under the command of God. The JudeoChristian moral code and its terminology differs from the libertarian one. That shouldn't be news. Of course our's view is correct and your's is wrong. That shouldn't be a stunning development to you either. The difference between the 9/11 hijackers and Joshua is rather crystal clear. They neither worship God nor did they receive any commands or sanction from God. ;-)
