John Chrysostom

"If he hath wronged thee at all." See where and when he has introduced the mention of the injury; last, after having said so many things in his behalf. For since the loss of money is particularly apt to annoy men, that he might not accuse him of this, (for it was most likely that it was spent,) then he brings in this, and says, "If he hath wronged thee."
