“Thou hast gained thy brother.” He did not say, Thou hast a sufficient revenge, but, “Thou hast gained thy brother,” to show that there is a common loss from the enmity. For He said not, “He hath gained himself only,” but, “thou too hast gained him,” whereby He showed that both the one and the other were losers before this, the one of his brother, the other of his own salvation.
