Exodus 21:23-25

21:23 But if there is serious injury, then you will give a life for a life, 21:24 eye for eye, tooth for tooth, hand for hand, foot for foot, 21:25 burn for burn, wound for wound, bruise for bruise. ¹ 

Deuteronomy 19:21

19:21 You must not show pity; the principle will be a life for a life, an eye for an eye, a tooth for a tooth, a hand for a hand, and a foot for a foot. ² 

Matthew 5:38

Retaliation

5:38 “You have heard that it was said, ‘An eye for an eye and a tooth for a tooth.’ ³ 

[21:25]  ¹ sn The text now introduces the Lex Talionis with cases that were not likely to have applied to the situation of the pregnant woman. See K. Luke, “Eye for Eye, Tooth for Tooth,” Indian Theological Studies 16 (1979): 326-43.

[19:21]  ² sn This kind of justice is commonly called lex talionis or “measure for measure” (cf. Exod 21:23-25; Lev 24:19-20). It is likely that it is the principle that is important and not always a strict application. That is, the punishment should fit the crime and it may do so by the payment of fines or other suitable and equitable compensation (cf. Exod 22:21; Num 35:31). See T. S. Frymer-Kensky, “Tit for Tat: The Principle of Equal Retribution in Near Eastern and Biblical Law,” BA 43 (1980): 230-34.
