Genesis 39:16

A proof of her fidelity, or an argument to gain credit, argumentum fidei. (Challoner) --- Love neglected, turns to fury. She wishes to take away Joseph's life, according to the laws of Egypt against adulterers. Diodorus says Sesostris burnt some women taken in the crime; and we must attribute it to divine Providence, that the enraged husband did not inflict instant death upon his slave. Perhaps he did not altogether believe him guilty. (Haydock)
