Tertull. adv. Marcion. ii. 18; Exod. xxi. 24. “Which of the good rules of the law should I rather defend, than those which heresy hath craved for her own purposes? As the rule of retaliation, requiring eye for eye, tooth for tooth, and bruise for bruise. There is no tinge here of any permission for repaying an injury in kind, but the whole drift of it is to restrain violence. That is, because that most stubborn and faithless people would count it hard or even inconceivable to await God’s redress, which the prophet was afterwards to proclaim, in the words, ‘Vengeance is mine, I will repay, saith the Lord;’ the commission of wrong during the interval was to be in a manner smothered by the fear of immediate retribution.” [Ante-Nicene Fathers, vol. III. p. 311.] St. Augustin (contr. Adim. c. 8), says the same in reply to the Manichæans.
