what's so fun about the bible is that you can find a quote saying just about anything you like, assuming there even was a jesus, he's also quoted in matthew as:
"Do not think that I came to bring peace on earth. I did not come to bring peace but a sword."
Hosea 13:16 - Samaria shall become desolate; for she hath rebelled against her God: they shall fall by the sword: their infants shall be dashed in pieces, and their women with child shall be ripped up.
Deuteronomy 2:34 - And we took all his cities at that time, and utterly destroyed the men, and the women, and the little ones, of every city, we left none to remain:
Deuteronomy 20:16-17 - But of the cities of these people, which the LORD thy God doth give thee for an inheritance, thou shalt save alive nothing that breatheth
Isaiah 14:21 - Prepare slaughter for his children for the iniquity of their fathers; that they do not rise, nor possess the land, nor fill the face of the world with cities.
I never said the Bible was consistent... It is actually one of the things I find fascinating about the whole thing. How does turn the other cheek square with old testament violence?
I know the easy answer, that it is all just made up, but even so these passages are two thousand years or so old and have been a major part of societies and cultures, which included many great thinkers and theologens more knowledgeable than me or any random person online.
Even if this is all a two thousand year old, self perpetuating delusion, that itself would be fascinating...
