You have heard that it was said, ‘Eye for eye, and tooth for tooth.’ But I tell you, do not resist an evil person. If anyone slaps you on the right cheek, turn to them the other cheek also. And if anyone wants to sue you and take your shirt, hand over your coat as well. If anyone forces you to go one mile, go with them two miles. Give to the one who asks you, and do not turn away from the one who wants to borrow from you. Matthew 5:38-42
“One of the [desert] fathers said, “If anyone asks you for something, and you give it to him, even if you are forced to give it, let your heart go with the gift, as it is written, ‘ if a man forces you to go with him one mile, go with him two.’ (Matt. 5:41). This means that if you are asked for anything, give it with a willing heart.”
