This message reminds us that Christ wants us to emphasize giving vis-a-vis taking. The Lex Talionis (Exodus 21:18-36, Leviticus 24:17-21 and Deuteronomy 19:15-21) said 'Don't take too much". But Jesus' message (Luke 6:27-29) was "Don't give too little".
Eye For An Eye, Sermon On The Mount, Turn The Other Cheek, Tooth For A Tooth, Lex Talionis
The scriptures in Exodus provide a limitation on unlimited vengeance being meted out when someone is wronged, however Jesus declared that even an eye for an eye was going too far - Jesus commands his followers to turn the other cheek - to not resist evil
Matthew 16:13-20, Deuteronomy 24:10-22
