“Why saidst thou, She is my sister? so I might have taken her to me to wife: now therefore behold thy wife, take her, and go thy way.”
King James Version (KJV)
12:17 And the Lord plagued Pharaoh and his house - Probably, those princes especially that had commended Sarai to Pharaoh. We are not told, particularly, what these plagues were; but, doubtless, there was something in the plagues themselves, or some explication added to them, sufficient to convince them that it was for Sarai's sake they were thus plagued.
12:18 What is this that thou hast done? - What an ill thing; how unbecoming a wife and good man! Why didst thou not tell me that she was thy wife? - Intimating, that if he had known that, he would not have taken her. It is a fault, too common among good people, to entertain suspicions of others beyond what there is cause for. We have often found more of virtue, honour, and conscience in some people, than we thought there was; and it ought to be a pleasure to us to be thus disappointed, as Abram was here, who found Pharaoh to be a better man than he expected.
12:20 And Pharaoh commanded his men concerning him - That is, he charged them not to injure him in any thing. And he appointed them, when Abram was disposed to return home, after the famine, to conduct him safe out of the country, as his convoy.
