“And he entreated Abram well for her sake: and he had sheep, and oxen, and he asses, and menservants, and maidservants, and she asses, and camels.”
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.
