Compare the Lex Talionis in the Torah:
"But if there is serious injury, you are to take life for life, 24 eye for eye, tooth for tooth, hand for hand, foot for foot, 25 burn for burn, wound for wound, bruise for bruise." (Exodus 21:23-25)
with the life of grace:
"You have heard that it was said, 'Eye for eye, and tooth for tooth.' 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. 40 And if someone wants to sue you and take your tunic, let him have your cloak as well. 41 If someone forces you to go one mile, go with him two miles. 42 Give to the one who asks you, and do not turn away from the one who wants to borrow from you.
43"You have heard that it was said, 'Love your neighbor and hate your enemy.' 44 But I tell you: Love your enemies[c] and pray for those who persecute you, 45 that you may be sons of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. 46 If you love those who love you, what reward will you get? Are not even the tax collectors doing that?" (Matthew 5:38-46)
