Oooh, boy.
Here's the scripture:
38 Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth:
39 But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.
Matthew 5:38-42,KJV
Where it's part of the Sermon on the Mount-in Luke, it's part of the injunction to "love your enemies." This is important: at that time, "your enemies," for Jesus's principally Hebrew audience, were the
Romans.
It's said by some that at that time, striking those perceived to be of a lower class was done with the back of the hand to assert authority-thus, the Romans would strike Hebrews with the back of the hand- and used their left hand for "unclean purposes," that is to say, to wipe their asses....if they were confronted by a Hebrew who turned their cheek, they were confounded: presented with a dilemma whereby they could strike with their open hand or fist:treating the Hebrew as an equal-in fact, the entire Sermon on the Mount is somewhat politically subversive in nature.
It also-since it's coupled with the verse from Deuteronomy about "an eye for an eye"-could be an injunction against vengeance, rather than self-defense. People used the verse from Deuteronomy to justify vengeance-thus the "
you have heard it said, rather than the more conventional, "
it is written" when referencing scripture.
It's also worth noting (for those who seem to think it's some sort of pacifist statement) that Jesus doesn't say to stand there and keep turning your cheek-he's pretty specific about the act.
Lastly, we have to note that Jesus told his followers this:
He said to them, “But now if you have a purse, take it, and also a bag; and if you don’t have a sword, sell your cloak and buy one.”Luke 22:36
Amazing to me how some people "read" the Bible, without actually READING the Bible.
