"but I say to you, offer no resistance to one who is evil"
Seems they are keeping to the theme.
The full context is
Mt 5:39 But I tell you, Do not resist an evil person. If someone strikes you on the right cheek, turn to him the other also.
A slap on the cheek is a serious insult but it's not damaging. It stings but doesn't hurt you. Jesus is saying that if you're insulted, walk away. He isn't talking about self defense.
